(CNN) -- The most difficult decision a member of Congress will ever have to make is to commit our nation's armed forces to military action against an enemy. Having served with and cared for those brave men and women as a physician in the Army Reserve with three deployments including Iraq, this is not a decision I would arrive at lightly or without careful consideration of all the available facts. There is no question that the horrific atrocities perpetrated by Bashar al-Assad's regime in Syria are nothing short of appalling and deserve international condemnation. But there is a glaring lack of international resolve on what the response to such abominable acts should be.

Rep. Joe Heck: World, so far, lacks resolve to respond to al-Assad regime atrocities
@highlight
He says he's not convinced U.S. should strike. Action should only protect U.S. interests
@highlight
He says a strike could spark wider regional conflict, escalate U.S. involvement

Heck: Iraq, Afghanistan, Libya show our intervention can leave behind further abuses
Rather, a strike on @placeholder must consider the greater strategic implications of military action and should be about one thing: the best strategic interests of the United States.
