Investigators say it was a revenge for NZ mosque massacre.
The Muslim terrorists consistently pick some recent event to claim as the trigger. Very often it's clear that that was just an excuse because the turnaround time is less than the time it would take to set up the attack.
That is probably the case here.
Sounds like bullshit. Usually Islamic terrorist attacks are part of a concerted an ongoing war effort. As a part of that war. That's almost all of them.
Now and again attacks are carried out by random loons. But those are so damn random. What the hell is the pattern? The Orlando attack on a gay club was carried out by a guy who it turns out was gay himself. What a shocker.
The Stockholm attack was carried out by a man who had been lying to his wife about how great his life was here and was no facing being shipped back home. Can't face the shame. What does he do? He becomes a radical Muslim within a month, finds a bullshit excuse for the attack and changes his mind in the middle of the attack. Decides he wants to live, gets out of the truck that was supposed to explode and runs away, only to get arrested in a petrol station he was loitering in because he didn't know what to do now.
Until there's more information forthcoming it's hard to form any conclusion about the Sri Lanka attacks. This is a tiny terrorist cell in a region where Muslims and non-Muslims have gotten on fine for a millennia. The whole thing is just strange. But it is a country that has been in a long civil war, capped off by a devastating tsunami. The country is also corrupt. The place is still a mess. Who the fuck knows the real background here? I wouldn't be surprised if the real reason was internal politics, and Muslims have been used as scapegoats.
