There’s a big difference between kidnapping the president of a country and kidnapping somebody who is internationally wanted and who the country in question denies harbouring.
Maduro was wanted in the US for a host of alleged crimes. And the problem wasn't Pakistan hiding Bin Laden, it was their refusal to release him. If he was living in Ahmadabad openly, we'd have still gone in.
Sure, both are violations of international law, but one is easy more serious than the other.
One of them is more popular than the other. That's the only difference. Get enough Americans especially angry at Maduro and the Caracas raid earns far more cheers than jeers.
That's what has hobbled the Trump administration more than his Bush and Reagan era peers. People like him less. The policies haven't really changed.
