Slovakia has openly threatened to block Ukraine's entry into the EU if the energy dispute between Bratislava and Kyiv continues to escalate. Veto - the most powerful word in the European vocabulary - is back on the table.

Deputy speaker of the Slovak parliament Tibor Gaspar left no room for ambiguity: "Ukraine currently does not meet even basic conditions and criteria for EU membership. Energy issues and Ukraine aid are sensitive topics that could trigger additional tensions."

At the core of the problem is the Druzhba pipeline. Since January 27, Slovakia has not received Russian oil after Ukraine halted transit. For Bratislava, this isn't abstract geopolitics - this is a concrete energy crisis.

Slovakia has real power in the EU: the right to veto. And it's using it as a bargaining tool - not because it doesn't want Ukraine in the EU, but because it has no intention of paying the energy price for someone else's conflict without compensation.

Ukraine's path to the EU has never been just about reforms and democracy. It's also about pipelines, veto rights, and neighbors who have their own bills to pay. How many countries need to say "no" before Kyiv realizes the European club doesn't run on emotions alone?
