It's called brainwashing, hate America "radicalization", and it's dark age, barbarian bullchit.<quoted text>After six months training the sumbitch could have created far better devices than shtty pressure cooker bombs. US Army EOD training doesn't take six months.

Deport all haters, back to where they hate from.
