Signing on without being absolutely certain

Boehner announces his support for the MEC's intent to fire a "shot across the bow" in Syria.

He's willing to jump on that bandwagon despite credible and growing substantiation that it was anti-Assad forces that staged the chemical-weapon attack.

Let's proceed carefully here.  The last thing we need is entanglement in another Mideast war based on mistaken intelligence.  Especially in a case where there seems to be no direct US national security interest.
