Big difference here, the US had made it know they were trying to Bin Laden for years.Wrong!!! Your article states he informed congress of the death of Bin Laden before he made the announcement to the public not about the actual mission. He actually entered another country without their knowledge to get Bin Laden and also didn't tell congress. Here is what really happened.

You were in such a hurry to condemn Trump and kiss Obama's ass you didn't read your own article.
Bin Laden was the leader of a terrorist group, while this was an attack on the leader of an entire country.
This was the first strike directly on an Iranian high up the chain, essentially, this was an act of war.
