If Putin wins, all hell breaks loose. There can only be peace if Ukraine gets hard guarantees, preferable NATO member. If not, Putin will make peace for now, restore his military and just give it another go. Europe must be able to defend itself as we can’t count on Trump and the US from now on. Both him and Elon seem to have a strong connection to Putin. We also should not be depending any longer on US made weapons.
Europe is building up its military, most of them well beyond the NATO limit by now, a few, like Poland, even beyond the USA. If it will be enough when shit hits the fan? I’m afraid not yet, but likely can put up at least something of a fight.
