Well, that's what he does, I suppose. He always try to find the countries that are least anti-Russian and try to divide EU - usually it used to be France and Germany, now it's Italy and Hungary. And then there is of course the case of the British, who generally are annoying af because they act like they hate being in EU but are to much of a coward to quit. Nevertheless, the bilateral agreements would be a start to create an army for countries that want to participate. Something like EUROFOR but that could actually do something. And even without the British with Germany, Poland, probably the Baltic states, France, Scandinavia, Belgium and the Netherlands on board such forces could pose quite a counterweight for possible Russian aggression especially in cases like we see in Ukraine. Note, that those would not be only used to defend borders, but to "defend European values" in EU, as well as in foreign countries, meaning they could possibly be used in situation like Ukraine now, without actually involving NATO (not to mention for countries like the Baltic states or Poland this could mean actual protection, something we cannot really count on NATO to provide)
