Karzai only looks like a fool when he verbally threatens a state that is larger, better armed, and has a well functioning military - unlike his own. A better way would be to increase cooperation with Pakistan, and make it politically painful for Pakistan to do nothing against the Taliban. But threats ... Pakistani generals thrive on threats, they receive them from all their neighbors now.
“Pakistan on its own holds India back”
Pakistan cannot hold India back. Its weak Indian govts, US pressure etc that hold India back. Remember US made pakistan a major ally after 9/11. US is feeding the snake now by donating f’16s and what not. Pakistan on its own can barely fart.
“Pakistan on its own holds India back, and that is something”
Holds India back? Am I to understand that you think India is some sort of threat that needs to be held in check by Pakistan? LOL Perhaps you should go live in Pakistan if you think it’s so wonderful.
