I agree that we got off topic because your comment was loaded and I had to give my point. just to backup my point I will add the Pakistan army's fight with the Communist Yemen along the border town of Sharrura in Saudi Araiba the whole infantry & air defence units of Pakistan army were stationed there and were directly involved in the fighting. So another countrys army did take part in another countrys war The other example is the UN mandate when countries send their armies to Afghanistan, Iraq and Kuwait. Whenever USA decides to invade Iran you should be sure to see UK jumping in to. With or without UN mandate. Again steering away from the discussion but I think clarification is in order.
