Yes "they" sided with Pakistan for the money, not the fact that Pakistan supposed to be an Islamic state. Yes, "they" sent its men to fight in Kashmir because they were paid to do so. Yes "they" fired at US invaders when the Pak. Army did not do jack to protect Pakistani soil yet the tribals were paid.
it's no wonder that Pakistan is tearing itself apart.
No, they were brainwashed by mullahs to send their kids to die all over the world & not just Kashmir+ wars are in their tribal customs & killing & dieing is not a big deal for them. As for their loyalty to Pakistan...they have no loyalty to anyone, & nor has anyone ever controlled these wild tribes since Alexander the Great.
