Second Hungary-Slovakia War

The Second Hungary-Slovakia War, also knowns as the Second Magyar-Slovak War and the 18 Day War was an armed conflict between the Slovak Republic and the Republic of Hungary which lasted eighteen days and ended in defeat for Slovakia. It lasted from the 22nd of August 2009 to the 10th of September 2009 and was the first and only war between members of both the European Union and NATO.

In OTL, on August 21st 2009, the President of Hungary attempted to visit the mainly Hungarian-speaking south of Slovakia where he was about to attend the unvieling of a statue of St Stephen, the First King of Hungary in the town of Komarno. The Slovaks were not amused by this as they felt as hough Hungary was claiming soiernty over Slovak soil and so refused the President of Hungary entry which damaged the two countries already strained relations.

But What if if the Hungarian President had tried to cross the border anyway, ignoring warnings from Slovak police, what if one of those police officers had an ichy trigger finger ?
