The only serious threat is China, not Russia - but the uniparty (including the Biden Crime Family) has been thoroughly compromised by the CCP. As a result, we are wasting our money and resources engaging in an escalating & potentially fatal pissing contest with Russia, over a country that is not a vital US interest...
“What’s past is prologue”
Your historical ignorance does not serve you well. Putin is trying to reassemble the Russian empire because whether a Czar, or Stalin or Putin, Russia has always felt a historical entitlement to rule over all the Slavs.
For the moment we might appease Putin by abandoning Ukraine. Are you naive enough to think he’ll stop there? I was just in Slovakia which is a much smaller country just south of Ukraine. They’re nervously looking north imagining the Russian military just on the other side of the border. Where does it stop?
China is also a threat that must be dealt with. US weakness invites aggression whether from China or Russia.
