The Infiltration of Radical Islamist Foreigners into the U.S.: Urgent Security Alert 2025. Radical Islamists such as the Muslim Brotherhood and CAIR
In recent years, an intense debate has arisen over immigration to the United States, particularly in relation to foreigners from Muslim-majority countries. Some argue that certain groups, especially radical Islamists, have entered the country with the aim of destabilizing it from within.
These claims include creating chaos in cities and states, failure to adapt to Western culture, and seeking positions of power at local, county, state and federal levels.
While these concerns have been amplified by conservative sources, there are also voices dismissing them as exaggerations or Islamophobia.
Below, we explore these issues based on available reports and opinions, representing perspectives from diverse sectors, including new evidence on organizations such as the Council on American-Islamic Relations (CAIR) and its alleged influence on U.S. policy.
The Entry of Foreigners and the Risk of Destabilization
Since 2021, under the Biden-Harris administration, there has been a reported significant increase in irregular immigration across the southern border. Sources such as the Department of Homeland Security (DHS) have identified emerging terrorist threats, including the possibility of Islamist radicals entering the country. For example, the DHS Homeland Threats 2025 Report highlights complexities in the terrorist landscape, with groups such as ISIS and Al-Qaeda potentially infiltrating. flsenate.gov
In addition, specific cases have been documented, such as the arrest of a Syrian national who posed a national security threat, or an Afghan migrant accused of planning attacks. fbi.gov

Conservative critics, such as former Congressman Randy Fine, have described this as an “invasion,” pointing to protesters with Hamas flags in New York as evidence of attempts at internal conquest. @RodGonz32785056
On social networks like X (formerly Twitter), users have warned of thousands of Islamists imported by Democrats, with goals of subverting the Constitution and imposing Sharia. @Care4USA331
However, debunking reports, such as those by the Carter Center, argue that many of these claims foster Islamophobia and do not reflect the reality of the majority of Muslim immigrants, who are seeking economic opportunity or refuge. cair.com
Creation of Chaos in States and Cities
Incidents of unrest linked to Muslim immigrants have been reported in several cities. For instance, protests against Executive Order 13769 (Trump’s “Muslim Ban”) in 2017 generated chaos at airports, though these were mostly peaceful. @EYakoby
Most recently, in Chicago, religious leaders have resisted ICE operations, which has escalated to violence and arrests. @MikeNew19512115
In Texas, a decrease in border crossings has been noted, but concerns about terrorist cells persist. gov.texas.gov
Conservative sources such as Fox News have highlighted Muslim candidates in Georgia as possible “jihadists” seeking to destabilize. foxnews.com

In contrast, organizations such as the ACLU point out that travel bans and mass deportations under previous administrations created more chaos than the immigrants themselves.
The FBI has emphasized that the problem is not Islam itself, but how extremists use it to radicalize. investigativeproject.org
CAIR, Muslim Brotherhood and Accusations of Links to Radical Islamist Groups
The Council on American-Islamic Relations (CAIR), founded in 1994 as the largest Muslim civil rights organization in the U.S., has been accused of having ties to radical groups such as Hamas and the Muslim Brotherhood. adl.org

During the 2007-2008 trial against the Holy Land Foundation (HLF), accused of funding Hamas, CAIR was named as an “unindicted co-conspirator.” extremism.gwu.edu
Documents revealed transfers of funds from HLF to CAIR in the 1990s and a 1994 memo linking it to a Muslim Brotherhood-affiliated “Palestine Committee.” flsenate.gov
Several former CAIR members have been convicted of extremist activities, including Ghassan Elashi(co-founder of CAIR-Texas, sentenced to 65 years for funding Hamas) and Randall Royer (former employee, convicted of supporting Lashkar-e-Taiba). investigativeproject.org justice.gov

Nihad Awad, executive director of CAIR, expressed support for Hamas in 1994, although he later qualified this. cair

CAIR denies these links, claiming to have no relationship with the Brotherhood or foreign groups, and has never been criminally charged.

Advocates see it as a legitimate civil rights organization, and the State Department does not consider it a terrorist organization.
Official Evidence and Linkage Signals
In 2009, the FBI cut ties with CAIR due to concerns about the HLF case. kslegislature.gov

In 2014, the United Arab Emirates designated CAIR as a terrorist organization, equating it with Al-Qaeda.
In November 2025, Texas Governor Greg Abbott proclaimed the Muslim Brotherhood and CAIR as state terrorist organizations, banning their operations and property acquisitions.

Congressmen including Elise Stefanik and Tom Cotton have called for federal investigations into alleged Hamas ties. cotton.senate.gov
Following Awad’s comments on October 7, 2023, the White House condemned his statements as “anti-Semitic” and cut off collaborations. nytimes.com
During Trump’s presidency (2017-2021), an attempt was made to designate the Muslim Brotherhood as a terrorist organization, pushed by allies such as Egypt, but failed to materialize due to lack of legal evidence and diplomatic complications. congress.gov
In 2025, Trump signed an executive order to evaluate Brotherhood chapter designations. whitehouse.gov
Critics see these efforts as politically motivated, while advocates argue that they protect national security. pomeps.org
Lack of Adaptation to Western Culture
Central to the criticism is the alleged resistance of some Muslims to integration. Studies such as the Harvard University study indicate that Muslims are not exceptionally resistant to integration, with levels similar to other immigrant groups. arabnews.com
However, Pew Research surveys show that Western audiences perceive Muslims as disrespectful to women, fueling cultural tensions. gov.texas.gov
On forums such as Reddit and Quora, there is debate as to whether or not Muslims assimilate, with some arguing that only a minority (5-10%) reject Western culture. billstatus.ls.state.ms.us
Commentators such as Momus Najmi claim that the teachings of Islam are incompatible with Western values. reliefweb.int
On the other hand, Gallup has found that many Muslims resent negative Western attitudes toward them, which could hinder integration. axios.com
The Quest for Power Positions
The rise of Muslim candidates in local and federal elections has generated alarm. In 2024, there was a “surge” of Muslim candidates in local elections, as in Teaneck, N.J. npr.org
Figures like Ilhan Omar and Rashida Tlaib have been accused of promoting anti-American agendas, even though they won elections democratically. @TECNORECRUITER
Organizations such as Muslim Americans in Public Service (MAPS) encourage Muslim political participation. gov.texas.gov
Since 9/11, American Muslims have gained unprecedented political and cultural influence. aljazeera.com
Critics like Laura Loomer see this as an “Islamification” of America, with candidates in Georgia described as “terrorists.” @BillyBubbadixie
However, the Brookings Institution urges American Muslims to learn lessons from the election for effective participation. youtube.com
Relations between CAIR and Zohran MamdaniZohran Mamdani, state assemblyman and mayor-elect of New York in 2025 (the first Muslim mayor in New York City), has had ties to CAIR. davisvanguard.org
During his campaign, PACs linked to CAIR, such as Unity and Justice Fund and Unity Lab PAC, donated more than $143,500. @rajyalaxmi9
These committees share staff and offices with CAIR, such as Basim Elkarra, former director of CAIR-California. yahoo.com.
Activist Linda Sarsour, a CAIR supporter, described herself as Mamdani’s “mentor” and claimed that her victory was due to “Muslim money” mobilized by CAIR. yahoo.com
CAIR celebrated its election as a “turning point” against Islamophobia. cair.com
Mamdani has participated in CAIR events and endorsed candidates such as Aber Kawas, a former CAIR staffer who minimized 9/11. foxnews.com
Critics, such as the New York Post, denounce these ties as evidence of radical influence. nypost.com
Mamdani and CAIR share critical stances toward Israel, but advocates see this as inclusive representation. aljazeera.com
CAIR polls indicate 97% of Muslims voted for Mamdani, highlighting his community support. aljazeera.com
Reality or Paranoia?
While there is evidence of real terrorist threats, such as those identified by the West Point Counterterrorism Center about groups like the Islamic Thinkers Society, fbi.gov
many claims of mass destabilization seem exaggerated. Sources such as the U.S. Institute of Peace attribute the lack of democracy in Muslim countries to historical and political factors, not inherently religious ones. billstatus.ls.state.ms.us
The allegations against CAIR and figures like Mamdani illustrate tensions between security and rights, with historical evidence of radical ties but no definitive federal convictions. cair.com
The debate underscores the need for a balance between security and human rights, avoiding divisive generalizations. Ultimately, successful integration depends on inclusive policies and vigilance against extremism of any origin.
