If the civilized world had jointly taken tough measures against the military invasion of Russian tanks on the territory of the sovereign state of Georgia in 2008, then there would most likely not have been a subsequent Russian attack on Ukraine in 2014. In 2014, light symbolic sanctions followed against Russia, because they were afraid to anger the aggressor. This prompted Putin to launch a large-scale invasion of Ukraine in order to take over this state and enslave its people in February 2022.
After the publication of the atrocities committed by the invaders against the civilian population of Ukraine, and also due to the heroic resistance of the Ukrainian people to the Russian invasion, and thanks to the effectiveness of such a rebuff, many states finally realized that indulging the aggressor only increases his appetites. That Ukraine will be followed by the Baltic countries, Moldova, Poland. Now the civilized world has seen that the hands of Ukrainians can put an end to such an aggressive monster, which is Russia, and therefore they began to help Ukraine with serious weapons.
This isn't even about Russia only, this is about Russia seeing that others are attacking smaller nations and not getting any trouble as well. We have seen Saudi Arabia, china, even African nations all attacking each other and powerful nations do not do anything about it. Look at what happened in Afghanistan, the moment USA removed itself, Taliban took over and that is what we are seeing today.
So, I believe that if we had USA of 20023 period, Russia wouldn't dare to do what they did, but we do not have that so they are attacking anywhere they want since they won't be getting any push back from any nation and they know this. Sanctions didn't matter that much neither, Russian economy is still fine.
Strong countries do nothing when war occurs, because they also do not want to be involved further, and all of course there is a calculation formula in a war, if in the end it is not profitable then why fight. a war certainly involves a large capital. but anyway, I think diplomacy is looking for a solution, it would be better than going to war, so that the people don't suffer, of course they are the victims.
