However, I'm disappointed that it looks like the cold war is heating up and there is a high possiblity of another war.
I'm always surprised when people react to the potential for war in a Trek story as evidence that war is inevitable. How many Star Trek
episodes have been about being on the brink of war and averting it at the last moment? "Balance of Terror" started with an act of war, but they managed to avert it in time. "Errand of Mercy" featured an actual shooting war that then got halted. On TNG, "The Defector" was about a barely averted war with the Romulans, and "The Wounded," "Journey's End," and probably others entailed barely averted wars with the Cardassians. On ENT, both "Cease Fire" and the Vulcan Reformation arc involved barely averted wars between Vulcan and Andoria, and the "Babel One" arc involved averting a war between Andoria and Tellar.
So Star Trek
often involves bringing nations to the brink of war, but only rarely does full-fledged war actually break out.
