He has veto power as Hungary is part of the EU. It might sound strange from the point of view of the big guy that doesn't even recognize the International Criminal Court, but in the EU small countries have a voice too, although in this case it sadly works against the common good.
We (Germany) don’t need Hungary to order a thousand Taurus and a hundred thousand Drones and hand them to Ukraine. We don’t need Hungary to negotiate a nuclear umbrella with France. We don’t need Hungary to cancel F35, which will probably never be delivered anyways.
Hungary, on the other Hand, needs Germany to pay most of their bills. It’s time to give Orban a taste of his own style.
You, Germany, need Hungary selling you Russian LNG, as you, Germany put your head up into your ass with sanctions against Russia.
You either change your position or your economy will continue to degrade and more of your factories will get closed and you will lose more positions on the market of automobiles and will get higher unemployment rate and higher unrest levels. And given your multicultural policy of welcoming Muslim immigrants - the unrest may get accelerated with just a few more "incidents" where someone rides into a crowd again or decides to start a jihad on some street in one of your cities.
Depends on whether Germany wants to participate in a war or prefers peace and good relations with countries important to their economy (either as one that sells them something or as one whose territory could be used as a market for the goods you produce and sell).
It's no more "strange" than US Senators from Wyoming or N Dakota or Vermont or Alaska having a veto. To pick one example, the US Senate veto is why the US consistently refused to recognize the Armenian genocide for many decades.
Hungary by no means has a veto on everything. The 27 EU member states vote on most issues by qualified majority (55% of member states = 15 countries, and >= 65% of total population). Only on a narrow set of issues (foreign, defense, finance, treaties, EU enlargement) they have a veto.
Who absorbed 5 million Ukrainian refugees? Europe, not the US. (Even Canada took more). And there could be millions more yet depending on the ceasefire/settlement arrangement.
Who paid € billions more in energy costs since 2022? Europe, not the US. [0][1] Germany in particular got crucified, and its manufacturing base fled to China (also in part due to the German Greens' historic Cold-War opposition to nuclear, nut that's a long story).
Funding Ukraine is not the "heavy lifting". The heavy lifting is when Putin invades Finland after taking Ukraine, and Germany and France are forced to respond militarily against a Russia aligned with the US.
