SBS News reports that United States President Donald Trump's Republican base is divided over his decision to join Israel's assault on Iran. On Sunday morning, 125 US aircraft dropped 14 'bunker buster' bombs on three Iranian nuclear sites: Fordow, Natanz and Isfahan. The strikes, which were carried out without consulting Congress, have caused some Republicans to break ranks with the president and join Democrats in criticising the move.

USSC CEO Dr Michael Green was quoted in the article saying that Trump's decision isn't unconstitutional and previous presidents have signed off on military intervention without bipartisan support.
