Since Russia Attacked Ukraine we appear to be in the 2nd Cold War now

I suppose you could also say that the ongoing cold war or hot war (your choice) between Iran and Hezbollah and the Houthis against Israel could be seen as a part of this but since this problem has existed now basically since the Ayatollah deposed the Shah of Iran in 1979 it's sort of been like this between Israel and Iran and Hezbollah and now the Houthis and other Shiite Muslims aligned with Iran now. So, I could say a Cold War between Iran and Israel has existed since the Shah of Iran was overthrown in 1979.

So, I would say that Russia invading Ukraine in 2014 was the "FORMAL?" beginning to the new Cold  World War which now includes Russia, China, North Korea and Iran and their allies against NATO and the U.S. and all their allies worldwide. So, this has created an entirely new world order than before in many ways.

This has devastated the Russian and Chinese economies so far and I'm sure Xi at this point wished Putin had NEVER invaded Ukraine to begin with. In fact, it is possible that Putin will be overthrown at some point because of what has happened and is happening in relation to Ukraine and NATO and the U.S. and other allies.
