May the innocent souls RIP.
It's not all Muslims involved in such terrorist activities and hence it's wrong to blame the entire community. I've heard of other religions too who take part in such activities as they are brainwashed. These terrorist groups kidnap children when they become 12-13 and keep provoking them to kill humans for their God and it's sad to see those kids being treated this way. The parents of such kids don't even get to meet their child and just see their child die due to these groups. It's the head of such terrorist groups who preach hate and evil. If they are executed, these activities would finally end.
So it's the religion to blame and their own stupidity. But these terrorist organisations are mostly political, as you can see they're not targeting countries in eastern Europe but the countries whos governments have been sticking their noses in other peoples business. Well there are extreme christian groups but I don't see them driving buses into crowds...
yes most of this terrorist act are been finance by evil politicians who arm is to "sticking their noses in other countries issue and business" Muslim as a religion is not the problem and the attack is not against the Muslim but against humanity. God cannot create human being with the intention of them killing themselves but to live in love and peace.
