This whole theater with Iran is a US geopolitical game. Israel should use it's channels to Russia to lower the level of aggression from Iran. Bombing and leaaving Syria in ruins will not make Israel more secure. It is already visible and reality that US has lost almost all influence in the world, specifically in ME, and Israel will have to face the security challanges by it self. How important will it be to have rather very good relation to Russia, instead of bagging the West for support. Many EU countries are not very much friendlier than Iran, but I do not hear from Israel open gramophone alike accisations against them. Israel should stop shouting accusations against Iran and demanding more sanctions, but rather communicate with them and address their real concern.
In face of illegal wars and interventions in ME, and in Europe, conducted by NATO, like in Yugoslavia, Ukraine, NATO expamsion to Russia's borders, incitement to Russo-phobia, the concern of Iran, and not only, is very genuine!
For Israel, it is not a question of choice! Israels perspective goes beyond Trump being couple years in office. It is a strategic question. The West definitively will loose the ability to dictate the world affairs it use to do over the last couple centuries. It is a paradigm change. Israel has to act wise.
