“Yes they can return.” Because you say so? When did you replace Zelynsky as president of Ukraine? More importantly, they don’t want to leave Israel any more than Palestinians want to leave Gaza. Frankly it doesn’t matter what you despise or think is illegal. But if it makes you feel better, keep bloviating.
I can only conclude that you are a bloodthirsty war-lover and apologist for murder, rape, kidnapping and mutilation. Have a nice life.
