My biggest concern is for what, exactly, does Trump’s adviser/s want to kick off nuclear testing? I wouldn’t be surprised if there’s talk in his circle about potentially using nuclear weapons if Trump re-takes the WH, & they may already be putting targets on certain “enemies”. Dangerous stuff.
First, a return to explosive nuclear testing by USA would likely result in most other nuclear states explosively testing.
USA has most extensive, & best instrumented, test record & thus most to lose.
2nd, good luck finding a test site b/c Las Vegas has grown enormously & made Nevada not usable.
