Oswald was an agent recruited and maintained by James Jesus Angleton, the CIA’s Chief of Counterintelligence.
The CIA taught Oswald Russian and then sent him into Russia (along with several other Americans btw) as a spy.
The notion that Oswald was a Communist was the cover story.
I don’t think the Russians bought it—kinda surprising any Americans were fooled either.
One amusing “clue” was that after Oswald was arrested in Dallas he asked for an attorney named Abt.
(Background: Oswald had tried to get his “Fair Play for Cuba” operation approved by the HQ of the Communist Party USA. They laughed at him—Oswald was an obvious agent provocateur.)
Nobody had ever heard of that attorney.
Abt was the in-house attorney for the Communist Party of the USA at the time—and of course would want nothing to do with Oswald.
It was Oswald trying to assure the CIA that he was still on the undercover “team”.
Oswald was not certain he had been set up and betrayed until Ruby’s bullet was heading straight at him.
If you want to read about Oswald from someone who actually knew him well (his mistress) this is the book to read:

If it wasn't Oswald from the Book Depository, where did the bullets that struck JFK and John Connally come from?
There is no credible theory other than the shooter firing from an elevated position to the rear of the limo.
If the bullet was fired from the front at roughly ground level, why didn't the windshield shatter and why wasn't the trailing vehicle and police motorcycles just a few feet behind not also struck? Even if the shooter was directly ahead in an elevated position, where could he have fired from in order to hit both Connally and JFK without breaking the windshield, or putting a hole in the backseat/trunk, or hitting the trailing vehicle or motorcycles?
If the bullets were fired from the rear at near ground level, from where? A trailing vehicle with two police motorcycles to either side were just a few feet behind the presidential limo blocking line-of-sight from the rear.
Where could the shooter have been in order to hit Connally and JFK but no one else inside the limo? There were six people inside the limo. Only two were hit, JFK and Connally sitting directly ahead of him. Why didn't the windshield shatter? Why isn't bullet damage to the limo consistent with any of the frontal or side attack theories?
If the bullets were fired from the right side on the Grassy Knoll, why wasn't Jackie, Connelly's wife, or the driver also struck, or at least covered in splatter?
If the bullets were fired from the right side from the top of the Grassy Knoll, from where could the shooter have been to hit Connally and JFK but not hit anyone sitting on the left side, or strike the vehicle on the left side? Furthermore, if the shooter was from anywhere to the right or left, how can the back-chest gunshot wound to Connally sitting directly ahead of JFK be explained?
If the bullets were fired from the left, where would the shooter(s) have to be to avoid missing Jackie, Connally's wife and the driver?
If the bullets were fired from either side, why doesn't the Zapruder film show his head jerking violently sideways? Furthermore, if JFK was shot from the front, why does the Zapruder film show the pink mist ahead of JFK rather than behind?
If the shooter was anywhere other than in an elevated position to the rear, how can bullet damage to the limo be explained?
The best explanation is that the shooter fired from an elevated position to the rear of the presidential limo.
