Ukraine attacking an Iranian ship in the Caspian Sea is a dangerous escalation that could pull the US into direct war with both Iran and Russia — bad news for everyone involved.

• Ukraine hit an Iranian vessel, saying it was payback for Iran giving Russia drones, then bragged about it openly.
• The likely real goal: merge the Iran war and the Ukraine war, so the US ends up fighting Russia directly — what Ukraine has wanted since 2022.
• The US is dangerously low on missile interceptors after arming Israel and Ukraine, which is why Trump just backed off bombing Iran.
• Trump is downplaying Russia's role in Iran's attacks, likely to avoid being cornered into retaliating against Russia.
• If all these wars merge, Iran would be fighting the US, Gulf states, Jordan, Israel, and Ukraine at once — a disaster for all sides.

Outlook: Trump will probably reject the bait, but he's stuck and tempted, so the risk of a wider war stays high.
