Oh we remember our history very clearly. We are currently in the most peaceful period of our continent since its colonization. And we clearly need that peace because the last wars on this continent were more bloodier and deathly than the ones before.
If Europe decides to return to ye old days there won’t just be a litte squabble at the edges - WW3 will happen! Don’t you realize that?
UA wants security guarantees. Deploying Western troops on their territory to secure the borders is a security guarantee.
That is what can prevent another attack by Russia. RUS would have to attack these troops to advance which would trigger not just a war against UA (again) but also against whom those troops belong to.
And yeah, UA needs more weapons.
