Though the US has condemned Russia's actions at every chance, President Joe Biden has gone to great lengths to make clear that US forces will not enter Ukraine and engage Russia directly.
Why's that? As Biden told NBC News earlier this month, "That's a world war when Americans and Russia start shooting at one another." In other words, the US' entrance into the conflict has the potential to touch off a global war.
Retired Lt. Gen. Mark Hertling, a national security and military analyst for CNN, told What Matters on Sunday, "The key to diplomacy is to limit the potential for war. While the current war of Russian illegal invasion into Ukraine is tragic, chaotic and devastating, it is still a regional conflict."
"If NATO or the US sent troops into Ukraine to help them fight the Russians, the dynamic would shift to a multinational conflict with potential global implications due to the nuclear power status of both US and Russia. Because of that, the US and NATO — and other nations around the world — are attempting to influence the success of Ukraine and the defeat of Russia by providing other types of support," Hertling said.
