Israel is clear about its intentions in Gaza – world leaders cannot plead ignorance of what is coming | Owen Jones

The UN is warning of a risk of genocide' against Palestinians. Future pleas of If I knew then what I know now' will not cut it

If I knew then what I know now. For many of the guilty men and women who plunged Iraq into blood and chaos, this became something of a stock phrase. When, in 2004, the then Tory leader, Michael Howard, was asked if he would still have supported the British government's motion backing the war - only 16 Conservative MPs rebelled a year earlier - he replied: If I knew then what I know now, that would have caused a difficulty. I couldn't have voted for that resolution." If I knew then what I know now, I would not have voted that way," protested Hillary Clinton during her doomed first campaign for the Democratic presidential nomination. If I knew then what I knew now, I wouldn't have voted for it," said Labour's then deputy leader, Harriet Harman, a few weeks later.

Prepare yourself for the revival of this phrase. As the calamity of Israel's onslaught against Gaza becomes apparent, those who cheered it on will panic about reputational damage and plead their earlier ignorance. Do not let them get away with it this time.
