What makes you say that? Tensions are pretty low at the moment.
Well, with the current President and the unprovoked murder of two US service people, I doubt we’d see such restraint. Carter is much different than most other US Presidents.
It's difficult to speculate about someone who is mentally unwell. Who knows; he actually seems to like Kim Jong Un, and dislikes people like, say, the prime minister of Denmark, but by and large it's just talk and tweets and not much action either way. Advisers are all over the place too.
We aren't at war with Iran right now, which we very well could be if Trump had reacted differently to them shooting down our drone earlier this summer.
This was 1976. Gerald Ford was president.
Oops, you are correct, Carter started the next year. I'm a bit too young to remember Ford, I do remember seeing Chevy Chase make fun of him once I got older.
The rate of 'tension' seems to change every month or so. I've noticed this produces a lot of apathy towards the situation.
