For the past few days I have been travelling through europe, mostly France Belgium and such, and to see the large military presence has certainly been thought provoking.
In France in particular, you couldn't move without bumping into a semi-automatic rifle (slight exaggeration but you get the picture). I haven't been to Europe in over 25 years and to see the army everywhere was quite sad. The need for them to protect is obvious. Talking to the locals, they shrug their shoulders while admitting it's sad but it's how it is now and how it has to be. They are constantly on terror alert and looking over their shoulders.
In Brussels, army were camped outside the train station. I felt pretty safe but it is a sad reflection on how time's are changing and the invisible terror no longer comes from countries with the threat of nuclear bombs but from strangers who have the belief what they are doing is for the good of their God :-(
