It didn't stop the Trump administration reimposing sanctions and a travel ban
They were looking for an excuse to return Cuba to full sanctions mode and they found one. The story spun to the American public was just proof that most of us are entirely gullible and primed to believe anything Cold War like, no matter how fantastic.
Now map that to "Russia's controlling our elections" and the like......or "spy chip in motherboard"....or 'Huawei's a national security threat"......you name it, we swallow it.
