It seems obvious. If the public were convinced that the Russians or Cubans were behind the assassination of the US President, that would be deemed an act of war. Necessitating a military response. In fact, some CTers alleged the involvement of Russia/Cuba was actually covered up and the blame placed solely on LHO to avoid a war. Any CTer (such as Mark Lane) who was attempting to convince the public of a fake conspiracy risked causing WWIII.
What have you been smoking now?
The topic based on that cornjecture should then be---

It seems obvious.
What is obvious to you is comical to everyone else here with any inkling of skepticism.
