Cairo - alBawaba - Islamic State, also known as Daesh, is "more overt" attempting to recruit fighters in South America, after the terrorist group losing ground in Iraq and Syria. Washington Examiner quoted the Republican Senator Joni Ernst saying "ISIS and its sympathizers are growing more overt in Latin America,". She wrote this to President Obama in a Monday letter. "Their increased use of messaging in Spanish and Portuguese, coupled with calls for terror in the region, exemplify ISIS' unwavering determination to change .." Ernst is an American politician who is the junior United States Senator from Iowa, elected in the November 2014 election. Ernst, a member of the Senate Armed Services Committee, sent the letter in advance of Obama's trip to Peru at the end of the week. He's traveling for an Asia Pacific Economic Summit that will be dominated by talk of trade deals and other issues, but Ernst wants him to prioritize national security. "With ISIS setting its sights on global expansion, and a history of Islamic extremism in the region, we cannot afford to continue turning a blind eye to these threats emerging right here in our own hemisphere," Ernst wrote. "You want to spread an extremist message in the Caribbean and recruit fighters for ISIL?" Navy Adm. Kurt Tidd, head of U.S. Southern Command, said in July. "We have a worrisome number of networks engaged in that." A group of Brazilian jihadists pledged allegiance to the Islamic State in July. "It should be clear to you by now that I do not support your measuring of our success against ISIS by the land they lose in the Middle East, as it is not an accurate representation of the progress we are making against Islamic extremist groups that wish to do us harm," she wrote.
