We just violated the international agreement that we agreed to when the last war ended and partitioned the territory of Russia’s close ally Serbia. I will agree that Russia has on many occassions gone out of its way to cause trouble. However, in Kosovo we are deliberately provoking Russia and invading her sphere of influence. We humiliated Russia here in 1999 - Putin will not want to shown to be weak like Yeltsin was. If WWIII starts over Kosovo it will be our fault.
Russia doesn’t have the right to interfere in Kosovo and Serbia anymore than it has the right to interfere in Georgia and Ukraine. Putin is intent on rebuilding the Soviet Union and he must be stopped at all costs even if that risks open hostilities between NATO and them.
And this, imo, made our leaders look like untrustworthy idiots in the light of the entire world.
