"Many East Asians believe that Trump started a war with Iran, giving Russia a huge benefit!"

This is certainly what is happening.

"I wonder why Trump is giving Putin the opportunity to stay in power for a long time!"

Both Putin and Trump are closely associated with Chabad Lubavitch, as are Zelensky and Netanyahu, so they are all co-religionists. However, both Putin and Trump are old, and I doubt they will be in power long.

Thanks!
