Buying Pakistan's Nukes

Bret Stephens (via Security Law Brief) proposes that we solve the problem posed by Pakistan's nukes by buying them, in exchange for an economic stimulus package of about $100 billion. Now the first thing you are probably wondering is why Pakistan would be willing to abandon its nukes in the face of the threat posed by India, a threat that prompted them to acquire the nukes in the first place. Stephens solution: extend our nuclear umbrella to include Pakistan. So...to get Pakistan to give up its nukes, we're going to aim ours (potentially) at our ally India? And we should propose this now, while India is quite justifiably upset with Pakistan over the Mumbai attacks? I appreciate Stephens' sincerity, but someone would have to be paying us to even try this.
