Preventing oil exports and increase insurance premiums for Russia's export economy, because Western sanctions clearly are unsuccessful in destroying the Russian economy.

My post history shows that I do support Russia's self defense against U.S./NATO threats. In my opinion Ukraine entering NATO is indeed an existential threat to Russia, because since (at least) the collapse of the UDSSR the U.S. and it's vassals openly communicated and pursued the goal of regime changing Russia (+ Belarus, Georgia).

How does Ukraine entering NATO constitute an existential threat to Russia? Do you think Ukraine + NATO is going to invade Russia?

What should NATO and the EU do to Russia, since Russia would like to break up NATO and the EU?
