The union of Romania with Moldova has always been a controversial subject that has aroused contradictory opinions and reactions, after the separation of the two after the Second World War.
In my opinion, a union of the two states would be a good thing for both countries and their citizens.
On the one hand, Romania and Moldova have always had a close connection, and their history is common, even though they are now different states. A big Romania like the one from the interwar period would do justice to the two neighboring countries.
Also, a union of Romania with Moldova would be beneficial from several points of view: politically, economically, militarily as it would form a large and powerful state with a greater significance in Europe and in the world.
On the other hand, for Romania it might be a small step back as Moldova is a net inferior economic, cultural or infrastructural country. So, Romania should "work" until it brings Moldova to the whole country.
In conclusion, a union of the two states would be a good thing for both countries, especially Moldova and Romania will have to strive to raise Moldova at the level of the whole country.
