During the International Armoured Vehicles conference held from 20 to 22 January in Farnborough near London, Romania announced plans to accelerate its main battle tank procurement programme.

The Romanians are in a similar position as the Poles - they are potentially on the 'front line' with Russia if Ukraine goes under the influence of the Russians, in addition, if Moldova comes under Russian influence/control as well. They are 'buffered' by Moldova today from Transnistria but that could change fairly quickly. Lastly, there is a chatter that Romania should consider 'absorbing' Moldova into Romania as it really is just a slice of Romania that Stalin took in 1940 (after it joining with Romania at the end of WW1 in 1918), which the Romanian's took back in the summer of '41 during their excursion into the Soviet Union with Nazi Germany, before Stalin taking it back again in the summer/fall of 1944.
Lastly, and most farfetched, is the fact that Hungary would still love to regain Transylvania again from Romania, which was theirs up until 1920. The Romanians are still 'concerned' that Hungary can't really be completely trusted still to this day.
There are over 1million ethnic Hungarians living within Romanian Transylvania today, which is about 18% of the population of Transylvania. When you look at this and then add in the over 750,000 Hungarians who live in Slovakia today (about 8% of the population), the ethnic Hungarians living in the 'Novi Sad' city and the province of Vojvodina of Serbia, which are another 200,000 and finally those ethnic Hungarians living in the former Czechoslovakia province of Sub-Carpathia with its former capital of Uzhgorod, which was seized from the Czechoslovaks in 1945 by Stalin and added to Ukraine, that's another 80,000 ethnic Hungarians. All told, that's 1m in Romania, 750k in Slovakia, 200k in Serbia and 80k in Ukraine, for a total of roughly 2million ethnic Hungarians living outside of Hungary. The number of 2 million people is about 21-22% of the current population of Hungary.
The current issue/'fight' between Hungary and Ukraine today (and why Hungary steadfastly stands with Putin on Ukraine), stems 100% from those ethnic Hungarians around the old city of Uzhgorod. There is 'talk' that Putin has 'promised' Hungary this area if they are successful in the retaking of Ukraine. Similar talk has surfaced a number of years ago with Putin and a former PM of Poland about Poland being 'given' the old Austro-Hungarian province of Galicia (capital city of Lvov/Lwow/Lemberg), the eastern portion that Stalin seized from Poland in 1945-47 and made part of Ukraine, if Russia was successful in retaking Ukraine and for Poland's 'help' in the matter.
Pre 1939 there was very large number of ethnic Germans living in Transylvania as well. The vast majority left (either by choice in 1944/45 or forcibly in 1945-47). Those that remained were basically 'sold' by Ceausescu to the West Germans (over 200,000) for the 'right' to immigrate to W Germany right up until 1989. By 'selling' I mean that W Germany paid Romania thousands of West German Deutsche marks per individual in a form of an 'exit visa'. This money was used by the Romanians in order to address their massive shortfalls in their economy. The German actress, Alexandra Maria Lara would be an example of one of these ethnic Germans from Transylvania.

I have 3 friends of ethnic German background who's parents or themselves came from Romanian Transylvania and where 'bought' by West Germany in the 1970's or 1980's and all settled in the area around Bamberg in West Germany, now just Germany.
The area around Hungary has the potential, though low, to become the next version of the Yugoslav Civil War because of the issues I've highlighted above.
