(They did not declare war on the Soviet Union though)
The three important findings are that Lee Harvey Oswald was the only shooter and that he acted alone, that Governor Connally probably had been wounded by the same "Magic Bullet" that killed Kennedy and that Jack Ruby had acted alone in the murder of Lee Oswald.
In short, The warren commission concluded that Lee Harvey Oswald acted alone.
Hope this helps !
