"The vast majority of refugees that are coming to the United States are from Syria and Iraq, some of whom may be aligned with the Islamic State, and who may wish to export their radical terror ideologies," Stern said.
On Sunday, Secretary of State John Kerry said the United States is planning to increase the number of Middle Eastern refugees it will take over the next two years by 15,000, which will bring the total number of refugees to 100,000 by 2017.
Over the summer, hundreds of thousands of refugees from Syria and other Middle Eastern countries have poured into Europe seeking to settle primarily in the more prosperous EU member states.
EU member states Hungary, Croatia and Slovenia, but also Germany and Austria, have tried to close their borders to the migrants, leaving smaller Balkan states like Serbia and Macedonia to deal with the refugees on their own.
Stern warned that while the United States always keeps an "open door policy" for refugees, the US government must be cautious to screen and not allow individuals that might be linked with terrorist groups.
"America has to walk a fine line to serve humanitarian needs, while simultaneously being careful to keep our own citizens secure," Stern said.
The Endowment for Middle East Truth is a US non-profit organization geared towards promoting Israel as the eastern outpost of Western democracy, the defender of the West against radical Islam, and the large benefit it brings to the United States in intelligence and tactical value in the continued US War on Terror, according to their website.
