Putin's decision to invade Ukraine gave new meaning to NATO. Since the beginning of the war, countries started to rearm themselves, including historical peaceful nations. The Russian conquering of Ukrainian territory, even under difficulties faced by the aggressor, ignited European needing to dedicate more budget and efforts to their defense. In the same way, if a ceasefire or a peace agreement were in next weeks signed by belligerent and interested countries, the fear of a new possible Russian invasion will remain.
On the other hand, as in his first term, Trump has done pressure toward more defense spending by NATO members. Obviously, it means that they must buy more weapons, military equipment, and defense systems from the United States, mainly, or form other countries. At the same time, he performs business trips selling American made products and opening markets, especially representing American defense companies.
Thus, any scenario drawn in the future will be translated into more defensive efforts and acquisition of military material, specially from the Americans enterprises.

Why might you be wrong?
If some European country decided to import more natural gas, in opposition to EU's policy.
