You are a fucking idiot. War's have started for a lot less.
This was a chemical attack on British Soil by a State Actor (Russia) with a military grade weapon. A MILITARY GRADE weapon.
It was an act of war. It was an extremely serious provocation. It was an attack on British Soil. It is indeed a casus belli.
There really isn't any hyperbole here. None at all.
And in addition. You are very serious issues and also double standards. You are talking about the entire Islamic faith as if they ALL subscribe to radical Islamic beliefs and all believe in a caliphate and want to wage war against the "infidel". This isn't true at all. nothing can be more false.And then you insinuate that Westerners don't blow themselves up in markets. well, westerners have also committed similar acts. Whether you talk about EOKA, or the IRA or even the Ku Klux Klan, there are indeed parallels with Islamic organisations such as Hezbollah, ISIL and Hamaz which btw you are a supporter of and do not even know it because you are too friggin dumb.
