Yes, it is in the interest of Ukraine, but that doesn't mean they're pushing for it or prove that Ukraine attacked Romania. And since these were Russian drones, are you suggesting that, unlike the previous times Russia bombed indiscriminately, this time Ukraine stole Russian drones and launched them at Romania?
As for the second part of your comment, your point is that Russia occupied and committed a genocide against that 'fake' country, when they became free tried to exercise soft power, failed, then invaded, but yet it's NATO that is waging war there?
The only part where you're right is that it is in NATO's interest that Ukraine keeps fighting, since it only costs us money, not people, while still killing the enemy. And that's why we're (and I include the EU here) giving them money, because we're terrified of what will happen when Russia is done with Ukraine.
