Well, they would surely feel more tempted of there is no naval cover. One thing is sinking a cargo ship. Other way more serious is targeting a ship that is close to a NATO war vessel and forcing it to defend.

They do not have the navy for that. Too few ships.

Escort duty requires a lot of ships to screen the protected ships.

Each ship will need a destroyer in range to defend it from missiles. There are a lot of cargo ships and romania does not have the numbers to protect all. Even the US navy would struggle to assign ships for that escort duty against an enemy like Russia, in the Black sea.

There is a treaty that forbids warships from non-balck sea countries for more than a few weeks if there is war. This is enforced by Turkey, as they control the entrance. It would be a nightmare for any Navy, even all of NATO navies, to rotate escorts in and out of the black sea that frequently.

Oh no, it was Ukrainian alright. But Russia expected to be able to hit Odessa from Sevastopol, a breach of the deal, without any form of clap back. And now they found out (again)

Maybe that is beacause the Iranian government decides to murder young people over religious fanatism. But sure, its the US fault.

Good, governments who actively try to topple the West for their own tyranical purposes and hatred have no business enjoying from Western ammeneties and events.
