First of all I want to note I am not a supporter of Putin .. and 100% agree that he does not deserve to hold onto power as of 2022 due to what he has done in Ukraine and in Iran, Belarus, Georgia, etc. ... he and the puppets he helps in the other places are keeping people down ... and as of 2022 it is clear he is the new Slobodan Milosevic.
... but are there any positives about Putin? Let's see ...
During the Iraq war era I have got to admit that I thought Putin then made sense ... he was ironically one of the strongest opponents of a stupid economy destroying war that the West STILL does not blame for the financial crisis it caused and for the ISIS mess that it spawned.
Sure Putin had launched a war in Chechnya ... but so did his predecessor Yeltsin. He also went to war briefly in Georgia ... but that was overshadowed by the horrors coming out of Iraq.
It was clear that circa 2003-2013 that Putin was often the least bad guy when compared to the Republican Party who invaded Iraq .. and the ISIS who took over Iraq. By 2014 it was clear Putin was becoming more of a problem. He had turned Russia into a dictatorship by refusing to stand down after a set amount of terms in office and was killing Russian opponents of him in and out of Russia. He then annexed Crimea. But ISIS, then another despot called Trump, Brexit and Covid all took attention away from Putin.
Ukraine was not the only country Putin has annexed ... he set up a puppet regime in Chechnya lead by Ramzan Kadyrov who is like ISIS but working for Putin. Putin also made sure his servant Ebrahim Raisi won an election in Iran with the help of his pal Trump destroying the popularly elected Rouhani administration ... and Iran's king Ali Khamenei making sure Putin's man got in as head of government. Now Iranians have to put up with a far worse regime than ever before .. seemingly constructed to keep the people, esp. women down. Putin also has clients in breakaway regions of Moldova and Georgia and the Kazathstan and Belarus regimes are more puppets similar to the Iranian one and the pre-Zelensky Ukraine one. Putin fought another war in Syria ... while it destroyed ISIS it cemented the Assads another Putin puppet. It all shows Putin will go to war if he has to in order to protect his clients.
Putin's worst oppression apart from war is felt on the streets of Tehran and Grozny where ISIS types oppress the local population on his behalf. He controls vital oil rich regions incl. the Arctic Ocean, Persian Gulf and Caspian Sea. He also wants to dominate the pipelines in Ukraine ... his aim is to be the dominant energy power in the world.
Because the world depends on the resources in Russia and its puppet states Putin may well get away with what he is at. He has always said if the sanctions go the oil flows ... it is hard to see people put up with misery and Putin knows this. Putin may win sanctions relief ...
... but what next? If the current puppet in Tehran keeps rolling back freedom in Persian lands ... whose people are educated and know what is going on and know it is Russia not Iran that is controlling them deliberately to keep them down ... expect a massive revolution. If Russia continue their war even if sanctions are gone expect it to become unpopular akin to how WW1 and Afghanistan became unpopular and changed Russia's system to the USSR first and Russian Federation second.
All in all ... objectively ... Putin is a bad guy. He may have had a purpose early on esp. during the Iraq war times. He may have helped defeat the worst of the ISIS regime ... but what he does in Ukraine, in Iran, in Georgia, in Belarus (Lukashenko is another lovely guy!!) and within his own borders negates any positives ...
