Yes, but ignoring one entire side of a war has seldom been considered clever.
Especially if your side is the one which lost the war.
Yet Serbian politicians recently put forth a constitution which contained a clause concerning Kosovo which they knew was beyond their power to enforce and would soon be rendered absurd by events on the ground. And since they haven't communicated to their electorate what we've been telling them for the last 6 years, they've now got a constitution which will keep them out of NATO and the EU until they amend it.
Par for the course for the Serbs, unfortunately.
