alt Hacker NewsThe EU, well NATO has the problem what Russia will do when it is no longer at war with Ukraine. There is also the question what the US would if Russia attacks a NATO country.
So European NATO countries basically need to keep supporting Ukraine while they try to becomes militarily independent of the US.
EU just needs to support Ukraine until Russia has dug themselves into a hole that will take generations to recover from. Their might be a point where the war hasn't ended but Russia is no longer seen as a threat by the EU.
