Exactly! Since when is the other party (the one not currently holding the White House) allowed to have their own foreign policy? WTF kind of BS is that!? Are they begging to be tried for treason? I'd arrest them the moment they set foot on US soil... What a bunch of dangerously power hungry idiots! Have they no idea the precedent they are setting? Of how they are damaging official US foreign policy?
I'd try them for treason, and if found guilty I'd have no qualms about executing them.
