The U.S. is sure Syria is responsible for last week's deadly chemical attack, but the politics of launching missiles to send a message is quite tricky.
Congressional leaders get a briefing today from senior White House and intelligence officials on exactly what evidence convinced the Obama Administration that the Assad government is responsible.
But President Obama tells PBS he's sure Syria's government was behind last week's deadly chemical attack.
Today congress finds out why Intelligence officials will share the evidence that hasn't yet gone public.
116 lawmakers - Democrats and Republicans - signed a letter pressuring the President to get Congressional approval before taking any military action. "We do not want to be involved ourselves and to mired down in a civil war," said Senator Bob Corker, (R) Tennessee.
Some military experts think limited strikes may be ineffective. "This is a symbolic gesture that will not necessarily improve the situation at all," said General Barry McCaffrey, U.S. Army, Retired.
President Obama insists something should be done. "There need to be international consequences," said the President.
The goal, however, remains unclear, but the White House says Syrian president Bashar al-Assad would not be the target. "The President needs to stick to his word, which is two years ago he said Bashar Assad must go," said Senator John McCain, (R) Arizona.
Great Britain was ready to vote on this today, but now wants to wait until the United Nations inspectors finish their report.
