He's not to blame for that, no, but he is largely responsible for the problem in the first place and certainly has some responsibility for the French apathy towards things. Why would the French go out of their way to stop a problem that is leaving their shores and heading towards the shores of a country that denigrated their union, left it for personal political gain, continually insulted them etc. We would do the same, wave the problem bye bye. When we were partners, allies, it was very different. Treat them with disdain and reap what you sow.
