You probably know more about the Romanian-Moldovan issue. There are some similarities here, too. But the differences are far more significant.
The Russians have been trying to reach the warm southern seas for 300 years. They've waged several wars here with Turkey, Iran, and Afghanistan, even reaching Pakistan. But they've failed each time.
Of course, we wanted to unite with South Azerbaijan.
But the problem is actually quite complex: Iran's disunity and weakening are dangerous for us, not just for the Persians. If Iran disintegrates, it's highly likely that Russia will immediately take advantage of this, quickly and easily gaining access to the Persian Gulf! And that can't be allowed to happen.
As long as Russia remains strong, plunging Iran into chaos is unwise.
Therein lies the dilemma!
In fact, all the region's problems (and there are many) can be resolved without wars and hostility. After all, we see the example of the European Union. It turns out that when countries start cooperating, all problems, even the most complex ones, resolve themselves. But where there are fanatical, so-called ayatollahs, talking about reason is pointless.
Look at the horrors our northern neighbor, the Russian ayatollah, has been perpetrating in Ukraine for four years now! What kind of reason are we even talking about?! It's as if the whole world is going crazy
