Romania's president Klaus Iohannis reiterated that Austria's arguments for blocking the accession of Romania and Bulgaria to the Schengen area do not hold water since it has accepted Croatia as a member of the border-free zone. President Iohannis also said he is not so sure about suing Austria...
Romania is the most enthusiastic supporter of the EU and is on an economic growth spurt right now. But sure, keep treating them like second-class Europeans until they start waxing nostalgic about the days they had a friend in Russia. See how that works out.
Bulgaria is already well on that path.
Your observations are pretty spot on, however the “friend in Russia” will most likely happen when hell freezes over. Russia is pretty hated and almost always was in Romania. What will however happen is the EU support will most likely drop to very low levels.
