Not likely, unless seriously provoked.

The US people don’t want it and wouldn’t support it without a really good reason (9/11 size). Plus (this is a little out of character for me but) I think they will become a powerful ally to the US in the future. They want to be more like the US and the best way to do that is to hop in bed with us. It will make for some uncommon pillow talk but if they want to have power, financial growth and freedom to continue their own plans they will make friends with the US and stay on our good side because the repercussions of a war may be bad for the US but would completely ruin them (war with Iraq as an example).
