If he means human history = US history then maybe. 1 out of those 5 are very US specific right now (racial unrest). The raging pandemic is once again regional where US is the worst globally but I'd not apply to the same to Europe and not at all to East Asia. The remaining 3 for sure a global problem but even then I do not think a chance for a nuclear war is higher than before say in the Cold War
