Oh yes, Reagan. The man who's non-response to the Marine barracks bombing in Beirut in 1983 was the true inspiration for 9/11. However he was telegenic so his fans forgave him.
No doubt Trump would have a similar non-response to Putin rolling all over Europe, and Trump's fans would forgive him.
BTW: Biden is not Marxist, regardless of what you hear from your alternative facts news sources. The economic difficulties at present are the result of supply chain tie-ups, Trump's fondness for tariffs whether they made sense or not, and the painful adjustment from a period of abnormally low interest rates and abnormally high stock market P/E ratios back to something closer to normal.
