Hamas posted a video on YouTube over the weekend showing its operatives preparing attacks on Israel while a song in Hebrew plays in the background threatening to “shock Israel’s security.”The propaganda clip begins with images of Hamas men preparing rockets and missiles presumably aimed at Israel. It then goes into a song with Hebrew language lyrics and Arabic subtitles.“Get up and commit attacks,” the jingle goes. “Get ready for shocks. Eliminate all of the Zionists. Shock Israel’s security. Try to engage the Zionist. Burn down the camps and the soldiers."
