Ok let me explain why he is reluctant:
1. There is no threat to america so he needs congress approval, http://www.theatlantic.com/politics...ut-congress-is-an-impeachable-offense/279160/ biden threatened to impeach bush in 2007. Now both men who stated clearly the president should not be allowed to attack a country without congress approving are the two men wondering whether they should attack without congress approval.
Conspiracy: i have not had time to fact check this but could biden benefit from obama attacking syria and then turning on him and calling for impeachment or perhaps that is impossible but i wonder if obama is being setup. Crazy conspiracy or is it?
All you've got are lying hypocritical politicians who mouthed off about congressional approval for political expediency. There will be no impeachment attempt lol
