Then let them take a public vote on the Authorization for Use of Force.
Absent that, we should hope they come to their senses and get US forces out of harms way.
There is absolutely no legal basis, US or International Law, for US Forces to be engaged in Syria...another Sovereign Country that Obama decided, unilaterally, to destroy.
What Obama wants is "law", and pretty much everyone in government feels that way. No one wants to be accused of being racist or an Islamophobe, so no one's brave enough to stop Obama's actions. Obama has "changed" the way our government works.
