The execution of the operation was blurry from the very beginning. The US Air Force was restricted to bomb whatever, in fear of provoking a Soviet/Chinese response. The US Military wanted a bombing that could show clear results. The people from Washington DC on the other hand, wanted to showcase their military strength, that North Vietnam could never match. Operation Rolling Thunder failed to undermine the government of Ho Chi Minh within the first few weeks, and so, there was a change in strategy. By the end of 1965, supply lines connecting the North to the South were being constantly bombed and there weren’t specific targets in North Vietnam itself, except Hanoi and Haiphong.
