US Republican presidential candidate Donald Trump called Monday for more strict immigration controls, including an ideological test for Muslims entering the country.

In his latest anti-Muslim rhetoric, Trump blamed Barack Obama and Hillary Clinton for the terrorist attacks, repeating his calls for strict measures against Muslim immigrants and visitors.

“My administration will aggressively pursue joint and coalition military operations to crush and destroy ISIS,” Donald Trump said in his latest speech in Youngstown, Ohio.

“International cooperation to cut off their funding, expanded intelligence sharing and cyberwarfare to disrupt and disable their propaganda and recruiting. It’s got to be stopped,” he added.

Referring to the Cold War era, Trump said: “We had an ideological screening test. The time is overdue to develop a new screening test for the threats we face today. I call it extreme, extreme vetting.”

This “extreme, extreme vetting”, as Trump calls it, targets “any hostile attitude toward our country or its principles, or who believed sharia law should supplant American law.”

He has also said that he would establish a commission on radical Islam to identify and explain to the American people the core convictions and beliefs of “radical Islam”.

Trumps controversial comments, however, have propelled Muslim-Americans to be actively involved in US politics and take a firm stance against him.
