Lee Harvey Oswald was responsible for killing/shooting John F. Kennedy.
He went to Texas to raise more Democratic Party presidential campaign funds, wanted to begin his little 'quest' for reelection, and because the Kennedy-Johnson ticket just barely won Texas.
Depends on the country, for example the UK Prime Minister is elected by the public.
Hope this helps.
The branches will depend on the country in question. Some have more than others. Some have them all merged into a single group. The following are the branches of the military in the United States: Army Navy Marines Air Force The Coast Guard is currently under the control of the Department of Defense but during peace time is under the control of the Department of Transportation. The predecessor of the coast guard was the Revenue Cutter Service. The Air Force came from the post World War 2 split of the Army and the Army Air Corps (the Air Corps becoming the Air Force). National Guard the army Navy Air force coast guard spec ops special forces special activities division national guard navy seals reconnaissance division Rifle divisions military relief land relief air relief In the US, we have Army, Navy, Air Force, Marines and during times of war, the Coast Guard.
