What Republican policies are good?

I am trying to come up with Republican policies in the last 80 years that have been good for our country.  Dems no problem- Social Security, medicare, Obamacare, clean air, clean water initiatives, etc.  For R's I can't think of a single thing that has been good.  Tax cuts- $18 tr deficit, no jobs, no booming economy.   Somalia, Iraq, Afghanistan,- disasters.   Can you think of any?  I'm guessing they must have done SOMETHING right but maybe I'm wrong.  Lemme know.
