Who is "we" and why should we do that? Should somebody also smuggle into Palestine supplies so that they can strike back at Israel with the same weapons they use? What about Syria? Would it be good that they can have the same weapons the US military (which happens to be occupying its country the same way Russia is occupying Ukraine) has to hit them back? Asking just out of curiosity.
