Trump administration told U.S. allies in Middle East about Israel's Iran strikes in advance

The State Department on Thursday informed multiple U.S.-allied governments in the Middle East in advance of Israel's strikes on Iran, four sources told CBS News. 

Secretary of State Marco Rubio personally reached out to a number of allies, the sources said.

The main message conveyed by the Trump administration in its outreach to allies was that the strikes were not a U.S. operation and did not involve American assets, and that the U.S. preferred diplomacy to military force.
