Explain how you know ( facts) this?
Let's look at an alternate ending to a tragic movie, an ending where millions of people didn't get incinerated in a nuclear war. First let's turn back the clock to 2008, when the Foreign Ministers of the NATO-Ukraine Commission met in Brussels, to discuss NATO-Ukraine relations. It was their decision that Ukraine should not be allowed to become a NATO member until they followed a membership action plan and make some changes to seal the deal. The alliance determined that Ukraine fell short and decided that they needed more reforms such as addressing the country’s political corruption “in a way that ensures domestic stability” before they could be granted NATO membership.
Now let's fast forward to 2019, and President Trump's "perfect phone call" with Zelensky. In that 30-minute phone call, President Trump asked the Ukrainian President to work with Attorney General William Barr in investigating the massive amount of corruption occurring in Ukraine, that which involved the Biden family in particular. Unfortunately that investigation never took place, and Ukraine continued to be known as one of the most corrupt countries in Eastern Europe. And NATO would still deny Ukraine membership into their organization.
Now do you think for a moment that Russia would have invaded Ukraine, had they addressed their corrupt dealings with a former Senator from Scranton, PA, his drug-addicted son, and his various other family members, and had been allowed entry into NATO? Not on your life. Had Trump been allowed to further press Zelensky into an investigation Ukraine's corruption, there would have been no "President Biden." There would have been no "Russian invasion." There would have been no "Ukraine War." And in all likelihood, there would have been no nuclear war, as could very well happen.
ETA: I didn't even mention President Trump's energy policies that allowed America to be energy-dominant. Did you know that he almost destroyed Russia's oil-based economy when he took the brakes off our own oil production? It's pretty hard for a little country like Russia to wage a war when they're having to dump their oil in the market at the same amount it costs to produce it. Elections do have consequences, and sometimes those consequences are unpleasant.
