Isn't it just time to quarantine Pakistan? Clearly, the country has not yet figured out what it wants to be and I don't think the US can really have much effect on that process. Pakistan has the bomb, of course, which makes things more complicated -- the world does not need a radical Islamic state armed with nuclear weapons -- but I think the current meltdown actually offers the US an opportunity to take a hard look at reality. The Obama administration has shown a real willingness to make pragmatic policy decisions and perhaps they will take a good look at Pakistan and tell themselves the truth. I'm sitting in a hotel room in Hanoi Vietnam as I write this and I'm thinking how American history might have been different had Lyndon Johnson taken a cold-eyed look at the Indochina war and decided to step back. Barack Obama has an opportunity for making a clear-eyed judgment that the US cannot effectively intervene in Pakistan or Afghanistan; that the best we can do is set a fence around those who would do us injury. That fence can be both diplomatic and military -- I am not a pacifist -- but it must not involve the escalation of the number of American soldiers. The administration ought to let it be known that Pakistan must decide its own direction, but that if one light is turned on in a nuclear facility, it will be instantly destroyed. Pakistan, Iraq, Afghanistan must all be confronted with existential choices -- their choices, not ours. Had the US taken such an existential position during Vietnam's civil war -- for that's what it was until the US and the Soviets made it a proxy war -- Vietnam would probably be a much more democratic place today. Had the US not backed French intervention in 1945, but instead had acceded to Ho Chi Minh's pleas for a guarantee of Vietnamese sovereignty, Ho Chi Minh might never have turned to the Soviets, whom he distrusted even while admiring Lenin's treatise on colonialism. If the US had not supported the French return to Indochina in 1945, the Vietnamese would have had to work out for themselves what their political destiny would be. I heard no less an authority than the old revolutionary and compatriot of Ho Chi Minh Huu Ngoc say just today in a lecture that had the French not been allowed back in -- with the blessing of the US -- that Vietnam would have taken a "capitalist," Western route, that that was Ho Chi Minh's preference. As it happens, I think there is a huge dose of revisionist history in that statement, but it is certain that things would not only have been different, but better, had Truman simply told the French to back off after World War II. Now the US needs to tell itself to back off, with the realization that there is literally nothing we can do to determine what sort of society the Pakistanis and the Afghans want to have. Morally it's none of our business; practically, it's a hopeless quagmire. All we can do is protect ourselves, which we ought to do vigorously, publicly, and transparently. The Vietnamese posed no threat to the US, except in out imaginations; the Afghans and the Pakistanis pose no threat, except in the case of the Pakistanis' nuclear arsenal, which ought to stand under the constant threat of annihilation should it be activated.
