Biden has pledged to focus like a laser on the pandemic in the US. He wants to get 100 million vaccinations in 100 days which is a herculean task. I hope he is up to the challenge.
I don't think he is going to do a lot of foreign policy matters (except to roll back some of Trump's doings) until the numbers in the US start going seriously down. Pretty sure we'll be well over 500,000 deaths before things really start turning around as we are already well over 400,000 deaths with the last 100,000 only taking about a month.
US is pinning all its hopes on the vaccines and is now pinning all its hopes on Biden to get the vaccines administered.
