Here are a few that come to mind . . .
(1) Our troops are out of Afghanistan finally. A twenty year war was ended.
(2) Legislative victories. These could actually be listed individual but I'll just include all of them under this one point. Some examples: the bipartisan infrastructure law, the American Rescue Plan, the climate/health spending bill, modest gun safety laws (federal action on this issue for the first time in thirty years), PACT Act, reauthorization of the Violence Against Women Act, etc. One could also list all the good outcomes of these new laws too.
(3) Positive economic news (3.7% unemployment rate, the creation of more jobs in one year than any other President in history, etc.).
(4) Strengthening of the NATO alliance and working to ensure we maintain a position of strength as it relates to Putin (which includes stiff economic sanctions).
(5) Confirmation of judicial nominees that many Americans support, including a new Supreme Court Hustice. This is especially relevant given the concerns many Americans have over the horrible Dobbs decision.
(6) Recommitted the USA to the Paris Agreement.
(7) Brought Ayman al-Zawahiri to justice in a very successful military operation.
