This story about Hungarian military spies gathering info for a Hungarian invasion story is ridiculous.
1. Hungary is in NATO. Whatever NATO knows we know it too.
2. Hungary had to renounce of all previous Hungarian lands in order to be accepted into EU and NATO. Especially NATO does not take states in which have border disputes.
3. Orbán, Szíjjártó and the Fidesz govt. has one good reason to bleet about peace and that the war has to be stopped, etc. If we hit hawkish tunes, right in that seconds the voices around will cry irredentism, and that Hungary wants to take back her historical lands, and this would drive a wedge in the relations with our neighbours. We can't have large military for the same reason, if we'd start to build up to a force of 200K we had in the final days of the communism, it would be cited as rearmament to get back the clay. We also participate in bunch of missions, most of these are peacekeeping, medical, technical whatever forces.

However, as I previously posted about this, I found it likely that NATO countries will occupy parts of Ukraine (the western corner, including Kárpátalja), where they'll enter citing humanitarian crisis, after the AFU collapses and people start to flee to the west. These NATO countries could include Hungary too, although I doubt even this.
