There are no more good options for the West against the likes of Russia+China. Economic sanctions just will not work, for economic sanctions should have been in place by 1950, so that Russia and China remain weak. But no, the fools of the West open door policy with China (Nixon) made China be the world's #1 economy. The western fools thought buying cheap products is a blessing, when in fact those cheap products gives China money to build bombs to bury the USA and Europe.
The question of will economic sanctions stop Russia from invading Ukraine? The fools of the West think and hope it will. But Ukraine to Russia is like the states of California, Texas, Iowa is to the breadbasket of the USA. So no, economic sanctions will not stop Russia from invading, just as the USA will not allow California, Texas, Iowa to be cut off from the rest of the USA.
Why did Putin wait until now to mass troops on the border of Ukraine? Why did he not do it while Trump was in office? For Trump would turn a blind eye on an invasion? Was it because Putin thought Trump would win the 2020 election and Trump ever more favorable to Moscow? I think it was for that reason that Putin waited until 2021 for Ukraine, the largest breadbasket of Europe. I think Putin thought Trump would be in power and even more agreeable to Moscow.
But the West is facing the Stark Reality-- they will lose all the countries surrounding Russia, for economic sanctions is no longer a punishment to a Russia+China.
Economic sanctions was a method of keeping Russia and China poor so that they would not be superpowers. It is of little to no use in economic sanctions once they are superpowers.
So all the countries surrounding Russia will now be invaded and China will invade Taiwan. Possibly even South Korea. Then they will work on Philippines, Vietnam, and much of Southeast Asia. Even raise the tension on India borders.
The ONLY REASONABLE Path for the West at this moment is to become a supernation of EU+USA plus all its allies forming one huge country that trades economically only within its allies. No trade with Russia and China and their allies. Make them poor is the economic sanction.
And in this manner, whenever Russia or China invades next-- our response is always the same-- YOU INVADE AND WE FLATTEN YOU.
So that the entire world is on a geopolitical course where Earth has two spheres of influence
The Good Guy countries EU+USA+UK+Canada+Australia+ NZ+ Japan+ India + + +.....
The Bad Guy countries Russia + China + North Korea + Iran + ........
Good Guy countries never buy anything from bad guy countries, never buy anything from them to make them poor and keep them poor.
And slowly but slowly as the years decades roll by, the bad guy countries want to join the Good Guy Block until finally in the future--- all countries are Good Guys.
