Taking on critics in his own party, Republican presidential contender Ted Cruz on Thursday defended Middle East dictators as useful allies against Islamic extremists during a Washington address decrying political correctness and stricter gun laws as an impediment to national security.

The first-term Texas senator described “America under attack” in remarks at a conservative think tank that spanned nearly an hour. He broke no new ground, but reinforced his view that global security depends upon an aggressive and engaged America — with distinct limits. The tea party firebrand did not call for additional U.S. ground troops to confront the Islamic State group in Iraq and Syria, preferring instead to intensify the U.S.-led air campaign and arm regional allies.
