It seems likely there will be an Israel-Hezbollah war sometime this year, with most of the probability mass by the end of September.
The resolution criteria on this question do not actually require a formal declaration of war, but seem to encapsulate circumstances that a reasonable person would consider to be a war.
Some countries are urging their citizens to leave or not travel to Lebanon due to the risk of war:

Israel has moved troops near to the border area and is carrying out military exercises simulating a war in Lebanon:

This is not something that I think the Russian military is or will become capable of over the next few years.
I do not think a 2nd Trump administration would withdraw from NATO, but even if it did, I don't think it would substantially raise the risk in absolute terms.
