What will happen if at the end Russia succeed in her conquest against Ukraine and take over the economy of Ukraine. That will extend the economic power of Russia no doubt and that will make Russia more powerful.
How will EU and NATO countries relate with Russia if that happens ?
It is literally a sort of economic interest that brought to something more agressive and even caused a war.
This war will obviously have losing results in both parties but to see it that Ukraine had suffered most and it makes them hard to recover fast than Russia.
and that will make Russia more powerful.
Russia is powerful already even before and they protect that power no matter how much it cost, even the lives of their people. And this Ukraine supposedly lives happy and free from the war if they stay neutral.
