Is there seriously some new cold war going on? I read in other media how some new American weapons can fight certain Russian tanks etc, and now I read about Putin bragging about his new weapons. My prediction for the post-Sovjet area was that the US and Russia would just leave each other in peace.
But they didn't. Or at least the U.S. didn't. Russia has warned for years that the US shouldn't be installing rocket shields so close to its borders. So the US has continued to antagonize Russia pretty much since the cold war was "over".
Now, Russia has started to interfere in US politics, possibly as a consequence of that, and it has also started showing its "might" in Europe.
This won't end well, if the two countries continue to antagonize each other.
