What is your angle here, because you jump from the EU being at war to the US dollar going higher? You do know that if Europe gets into any war, the USA will be with them and vice versa. However if we ever reach that point, the whole world will be in an unrecognizable state compared to the peace we have now. It's amazing how many warmongers seem to exist in this economic section, but then I get the feeling that a lot of them are Russian propagandists who are embarrassed at how badly their country is failing in a war with their direct neighbor. This is what happens when you continue supporting a crazy dictator and your comrades are too weak to rise up and overthrow the evil that is suppressing you.
Whether Europe will enter the war that has been going on between Russia and Ukraine for the third year now depends entirely on Russia's actions. European countries will continue to provide assistance to Ukraine in its defense against Russian military aggression. If Putin and his entourage want to ignite the flames of war, they will in any case come up with a pretext for this.
On the one hand, Russia is slowly running out of steam in its offensive potential, its armored vehicles will last no more than a year of war of the same intensity, its professional army has been virtually destroyed. But it still has enough mobilization human resources and the ability to send untrained soldiers to storm the positions of the Ukrainian Armed Forces.
On the other hand, Russia is uncomfortable with the fact that it is suffering defeat from a relatively small Ukraine, and therefore the Kremlin is constantly inventing fakes that there are no Ukrainians left at the front, that Russia is already fighting with representatives of NATO countries there, and therefore the residents of the Kursk region of Russia, where the Ukrainian Armed Forces entered, were surprised to see Ukrainians in front of them. True, Putin recently stated that if the West gives Ukraine the opportunity to fire its long-range missiles deep into Russian territory, this will be regarded as direct participation in the war. That is, it is thus recognized that there are no soldiers from these countries on the battlefield from the Ukrainian side. In order to justify its military failures to its population, the Kremlin may expand the conflict and provoke another war with Europe, despite the fact that Russia does not have the strength for this.
