More than three months ago, Russian President Vladimir Putin's national security adviser Nikolai Patrushev gave his Israeli counterpart a document. It contained an unofficial proposal for a deal between the U.S. and Russia on Syria and Iran intended to start a wider dialogue between Washington and Moscow to improve relations, two Israeli officials with direct knowledge tell me.
Why it matters: The Russian proposal would have tied a U.S. withdrawal from Syria to an Iranian exit from the country, and provided the U.S. and Israel more influence over a future political settlement in Syria. However, it also called for a freeze on U.S. sanctions on Iran — something Netanyahu found unacceptable. Ultimately, the U.S. gave up much of its leverage in Syria with President Trump's surprise announcement Wednesday of a unilateral withdrawal.
