I have no problem with the B and the D, and I applaud those who refuse to do business with companies and individuals associated with the oppression of the Palestinians and who liquidate investments in Israeli firms. That's a proper and peaceful exercise of their rights. But we advocates of liberty should draw the line at S sanctions because we should on principle reject the state's power to impose sanctions on anyone. Sanctions punish people who don't wish to boycott the targets. But the right to boycott logically entails the right not to boycott. Also, if the state has the sanction power, it will surely use it against targets we wouldn't want targeted.
I propose a different S instead: Strip Israel of its $3.8 billion annual military appropriation.
