Putin Says They Have Crossed the Redline and Now Its Our Turn

Russian President Vladimir Putin has warned that Russia will act if NATO crosses its "red lines" on Ukraine. However, a Russian envoy to the United Nations has also claimed that the US has already crossed Putin's red lines in the Ukraine war. 

Putin himself has stated that his red line was crossed when Ukraine began mobilizing troops near the border with Russia. Some experts believe that Putin's red lines are actually a roadmap to Russian defeat in Ukraine, while others argue that he doesn't have any red lines at all.
