safe versus unsafe unclear weapons

""These are agonising struggles among and within peoples, to which the west has contributed nothing but hostility and belligerence. Under the cloak of "counter-terror", it has been as crass as it was during the Crusades. Of course no one wants to see nuclear weapons spread. Russia tried to stop China getting them. China tried to stop North Korea. The west tried to stop India and Pakistan, while hypocritically tolerating Israel and the replenished arsenals of France and Britain. No pressure made the slightest difference to anyone.""
