If the UK falls under brutal Sharia Law, should America use military force to intervene? (I know this is near-impossible, but say a violent minority coupled with weakening government and deteriorating military in the UK)
Nope. Not our problem.
Yes, even though they brought it on themselves by bending over backwards to be fair and other bullcrap PC ideas. Just like is happening here.
Yes. If any violent group were to be en route to crippling our closest ally, I would be all for military intervention.
