As President Barack Obama considers possible military intervention in Syria, members of the Massachusetts congressional delegation are urging varying levels of caution.

Massachusetts Senator Elizabeth Warren called Syrian President Bashar Assad’s alleged use of chemical weapons reprehensible, but warned:

“It is critically important that before we act, that we have a plan, a goal and a reasonable way of achieving that goal,” Warren said.

Warren says any action in the Middle East could lead to problems.

“We might have good intentions, but the consequences of our acts are not limited by those intentions,” she said.

Sen. Ed Markey, who is a member of the foreign relations committee, says he would support a “surgical strike."

“It is important for the U.S. to stand up and say no, chemical weapons cannot be used," Markey said. "At the same time, we do not want to involve ourselves with ground troops in a civil war in Syria.”

Massachusetts Representative Stephen Lynch, of South Boston, says the U.S. shouldn’t act unilaterally:

"I certainly don’t think the United States should go in there without considerable international support and probably with full NATO support,” Lynch said.

U.S. Reps. Mike Capuano and John Tierney insist the president consult Congress before going forward with a military strike.
