I'm not sure what to think about it.
Additionally to this, with Croatia and us, Serbia is involved in a new initiative to stop the migration at the border of Macedonia. And there is another one, which includes Austria, and involves the Bulgarian border. This also complicates things, and can derail the cooperation. Obviously no foreign troops will go there if war breaks out. At least I highly doubt they would go there.
Should be noted that NATO organized a new HQ in Bavaria to be command central for the Eastern Euro troops, where more units were directed as well. There is a chance that they'll enter Ukraine at one point and create a safe zone in western Ukraine. But... if they are here, they could be used against Serbia too.
Is Europe spiraling into a war again?

On the Belarus front it could be enough to just sit there and bombard with artillery. They might be able to reach Kiev, I've no idea about the capabilities. Still Belarus would suffer losses, and the popular support of Luka, could fall more if it is possible.
With Russia they just signed some stuff which creates a common economical union. Maybe some embargo can be outsmarted by Belarus being a facade for purchases.
Meanwhile Moscow stopped shipping oil to countries who introduced pricecap on their oil.
