As it is very possible that the mad Mexican President may very well say "WELL WE'LL BOMB YOU TOO" and that you are allies with them, would you be defending them from the consequences of declaring war against our nation? I sincerely hope not, as Mexico seems to have allied with the powers of chaos that you seem so against.
Regarding C.O.P.E, what is it exactly? A defensive alliance? Could we possibly join as an observing member?
