So that is how the US War with Mexico began in 1846: “US, Soviet soldiers link up and the Mexican-American War begins.” Ah, the joys of time-travel and alternate history.
;)
The Mexican war happened at a time when Mexico was disfunctional. ..oh, wait a minute... They still are disfunctional. Ok, but at that time they were ruled by Santa Ana, who was a dictator who took over Mexico following a revolution. Mexico has experienced a lot of revolutions. Having a Wall between the USA and Mexico would help prevent spill-over from the next Mexican revolution, civil war, or anarchy. LETS BUILD THE WALL.
1944: When an Army Air Forces plane carrying wounded British soldiers goes down 100 miles behind Japanese lines in Burma, Lt. Carter Harmon conducts the first known military helicopter rescue. His YR-4B helicopter can carry only one passenger, so Harmon has to fly four trips to everyone back to safety.

Rick Monday rescues the flag. Love Tommy Lasorda in this video. No surprise that Ken Burns omitted Monday’s flag rescue in his Baseball documentary series.
