I didn't expect Putin would dare to invade. Even though most of the forces were moved, even from the Far Eastern Military District.
Initial successes at Gostomel airport, but also apparently the spearhead failed to reach that location in time. It seems they wanted to topple the government in Kiev within days. This failed totally, and in the North the population was very unfriendly, so they withdrew. In the South they had more success. But in general most of the population does not like them. This is something they got totally wrong.
In general Russians failed to execute the modern warfare, they needed more UAV's..
U.S. and NATO can send new weaponry to Ukraine indefinitely, it is small change/nothing to them. And now the image of the Russian army is damaged..
If Russia are a paper tiger, so is China.. China still doesn't have such capacity of moving the troops around.
Already for a decade, I heard opinions of various think thanks, that one of the big challenges of the 2020's will be to deal and secure the Russian nuclear arsenal after the estimated dissolution of Russia (which was to happen after Putin was no longer in power)..
The West has secured in Ukraine an anti-Russian nation, and as strategists said long ago, without Ukraine Russia is not a power.
On the other hand the Russians had the chance to exert their influence in Ukraine, and they failed.
At the end of the day. Russia has served as a scarecrow for the expansion and the continued existence of NATO. Definitely if Russia is eliminated as a power, the likely will happen to China.
In EU, some nations such as Poland due to the existence of Russian scarecrow have been allowed to act in a "sovereigntist" way. without Russia Poland will be stamped on. And that "50 %" of Polish owned media, will turn into 1 or whatever % of Polish media owned by the Poles..
All in all, the elimination of Russia-China axis will also mean the elimination of the West, or the reformulation of the West. The entire concept of the nation state will be eliminated (as it is also a backward 18th-19th century concept), and the world will be run by international corporations, and nation states will be reduced to a mere formality, or be under the umbrella of an international organization.
The globalization and elimination of all nations due to some of these events might be realized much sooner than anticipated. The only thing that can offset this is some sort of a radical event (i.e. nuclear war etc.).
