If Putin were wise he would take advantage of cultural similarities between former soviet union countries to form a version of the EU block. He totally destroyed that plan by attacking Ukraine. He proved he was much weaker to invade Ukraine and then expand it to form a new soviet union. The war has also changed Putin’s relationship with China. He is now in a terrible situation. He is out of the equation to realize the idea of the soviet union block. He has no power or legitimacy to form it. This idea is good for Russians and people living in former Soviet Union countries. However, Putin has eliminated himself out of the equation.
UPDATE 1:
The Zangezur corridor was probably mentioned again to push parallelism toward Iran’s regime and unite them against establishing new borderlines. However, what it did was push Putin toward a vulnerable situation.
