Indeed, there was a lot of neighbouring countries to Russia that wanted payback for past grievences (including Poland) yet let it slide to agree with that consensus even knowing fully that Russians haven't agreed to it, nor believed Russians ever would limit themselves like that and got it hammered down by the west whenever it was mentioned.
Now Putin opened Pandora's box by invading a major European country under the pretext of switching it's government.
It's not 1945 anymore where most European states are tired and exhausted of a world war.
This triggered the potential for not only that Russia would invade other major European states, but also forces all major European states to decide wether to want to continue this consensus (practically being against Russia's invasion of Ukraine) or by aiding Russia as much as possible (caused by wanting to invade major European states themselves)
Which is why it has put Hungary and Serbia in a bad light in Europe, and also a little bit ridiculing cause they got no chance to invade any major European state.
However countries bordering Hungary and Serbia are certainly far more alert then before due to those actions.
So if a state like Spain suddenly would increase it's military, side with Russia diplomatically, then Portugal, France and Italy + Morocco would be highly alert about it.
