Not possible. Not even remotely.
Its not only possible, its a near certainty. Not as in an Iraq style takeover. It will be a massive “secure the nukes” operation. They are stored in a dissassembled state an monitored by us. Any realistic threat they will fall into the hands of a Taliban style revolt will trigger an immediate USA raid. A strong force of US troops secure the site and remove the weapons, and our air wipes out the Paki AF if they remotely threaten the OP.
Then we leave, we wont try to seize and hold. And Pakistan is immense in Population and size compared to Iraq.
