Israel does not have B2s or any pilots trained to fly the B2. By doing it ourselves it gets done (fulfilling America's decades old objective to de-nuke Iran) without risk of revealing any B2 technology and all of the other US Mil support systems that were required to make this complex plan execute flawlessly. Surgical. Quick and clean. Problem solved, no more Iranian nuclear program to terrorize all other countries in the middle east. No loss of American life or hardware. Israel can send in their troops for the dirty boots on the ground work. If Iran bombs any of our bases, Trump will bomb the hell out of numerous exposed Iranian assets. Again, no American boots on the ground. The art of the deal... Ayatollah should have taken the deal. Now he finds out. Trump discussed outcomes with Putin, Xi and all other middle east leaders (Saudi, Qatar, etc) long before taking action. Diplomacy with a big stick. I think Trump will come out of this unscathed politically, actually gains respect with all world leaders.
