What is Russia's Long Term goal regarding Ukraine, Syria and other countries?

 Is Putin's goal to keep Syria in under Russian influence?

Is Crimea to resupply Syria so this war can go on for years and years against Sunnis and others in the Middle East?

Is Putin's goal to take more than just a corridor in Ukraine so he can drive trucks to Crimea to resupply ships to Syria?

How many countries is Putin actually after?

Or is he eventually after the whole world after destroying the value of the dollar internationally?

What is Putin's long term goal now he is sending Russian soldiers into die in Ukraine along with Ukrainian soldiers. Because only Russian parents who receive their soldier's dead body have any clue that something is going on. Because it is not in the news in any way we would recognize at all here in the western world.
