Israel reportedly struck targets in southern Lebanon again on Wednesday, brushing off warnings from Donald Trump and threatening to derail the US peace process with Iran.

Israeli forces were said to have carried out an airstrike in the Nabatieh district and raids on the town of Nabatieh al-Fawqa, according to Lebanese media and Al Jazeera Arabic.

There was no immediate comment from Israel. Iran has warned of a “hard response” if Israel does not stop its attacks on Lebanon, and Hezbollah says Tehran promised it would not sign the final nuclear deal with the US unless Israel stops.

1. Under the circumstances, then wouldn't the dynamic of a "proxy war"

between Iran and Israel shift to a "war" between those two countries?

IOW, if Iran decided to concentrate on bombing sovereign Israel in response to Israel bombing Lebanon, would or wouldn't the United States (Trump) stay out of it?
