The main reason why the Ho Chi Minh Trail was important to the North Vietnamese and the NLF was because it provided for vital supply lines for the Viet Cong during the war.
Basically. They had the biggest ego ever. The North knew that they had the more resources and the more superior military force. So they basically underestimated the South. Also it was due to the North's military generals. They didn't lead the troops the right way and all in all, that led to early Confederate victory. The South had the superior military leadership against the North.
The Speaker of the House is next in line because the House of Representatives was traditionally seen as the "people's house" or the most Democratic house. It wasn't until the early 20th Century that the Senate was elected by the people directly, so the leader of the more Democratic house was a fairer pick in the line of succession.
