France saw the opportunity to confront the US and in doing so, raise it's international stature....a political powerplay which will, in the end, cost them deeply.
The worst relationship you can have is one with someone who claims to be your friend, but looks only to serve themselves....the French government will reap what it sows. Those currently in power are not only cowards, void of a spine, but also are lacking the character which is necessary to achieve the status they so dearly want.
To disagree with the US is fine....to openly and actively stand in our way and thru that effort cause us harm is, well, deserving of a response. That day of reckoning is coming.
