What are the main causes of vietnam war and korean war?

After WWII and the decolonization period, both Vietnam and Korea were split up. The Northern section of both Korea and Vietnam were ruled by communist regimes. The Southern sections were Democratic/Republic governments.  The Vietnam rulers wanted to unit North and South Vietnam together, but under their own government, and the same with the two Koreas. After Russia builds their first Atomic bomb, though well after America's, Russia gives North Korea a go to attack South Korea. The UN immediately sends a makeshift army from multiple countries to support South Korea, and they battle back and forth until 1953, when the borders are the same as today's. This was about the exact same story with the Vietnam war, except Southern Vietnam immediately collapsed when President Richard Nixon pulled US troops out of Vietnam. These 2 wars were a series of conflicts between communist and non-communist regimes with Russia and US support known as the Cold War.

on 6 november american voters will elect members of the house of representatives and the senate, which together are called congress.

both houses of congress are currently controlled by the republican party, which backs president donald trump.

the democrats think they can win control of the house of representatives this year by winning a majority of seats.

doing so would let them block or delay the president’s plans by refusing to enact them.

all 435 seats in the house of representatives are up for election.

if the democrats want to take control of the house by having the most seats, they’re going to have to claim at least 23 from the republicans.
