I just want to point out that the US calling a group terrorist doesn't necessarily mean that the said group is terrorising people or is plotting attacks in western countries or whatever. It just means they are armed and the US does not like them. Some of these "terrorist groups" are official branches of their countries' armies. Some of them face rival groups which do the exact same things but are not "terrorist groups" because they follow goals similar to those of the US in the region. Of course, you guys know all this, it just gets forgotten very often.
