And do u guys even know why US prez is called commander in Chief??? If the prez can't go to war without congressinal vote just take out the commander of chief tag from his post but War power resolution provides him that tag. and yes he can act alone for military intervention. It has been proven many times in US history be it be in Bosnia, Haiti, Somalia, Panama, Libya, Lebanon or Iran. Comparing Britains PM to US Prez by illumnation is a complete BS. Thats what I have been trying to prove but again I don't like wars.
