That’s a real long way away. Ukraine would still have to address deep systemic corruption and democracy related problems. To join the EU, there’s also consideration for public debt as a percentage of GDP (Ukrainian will require a lot of loans to rebuild after the war). That’s assuming the EU (hopefully) dodges the upcoming eurozone crisis (Italy’s debt crisis, probable recession in Germany, energy crisis, migrant crisis, fascist governments in Italy and Hungary, inflation, etc).
