WASHINGTON (AP) — Only 1 in 5 Americans believe that failing to respond to chemical weapons attacks in Syria would embolden other rogue governments, rejecting the heart of a weeks-long White House campaign for U.S. military strikes, an Associated Press poll has concluded.

The poll of 1,007 adults nationwide found that most Americans oppose even a limited attack on Syria — likely with cruise missiles — despite Obama administration warnings that inaction would risk national security and ignore a gruesome humanitarian crisis. And a slim majority — 53 percent — fear that a strike would lead to a long-term U.S. military commitment in Syria.
