The latest desperate claim to relevance comes from Islamic Jihad, which is taking credit for a drop in the "Zionist Stock Exchange."
As the current operation started, the Tel Aviv Stock Exchange dipped by 1.9%. About half of that loss was made up yesterday.
To give an idea of how huge a blow this must have been to the Israeli economy, here is the chart for the TASE during the past year:
More seriously, the real story really is that terror groups hate being irrelevant. This is important because they will become more and more desperate to find ways of attacking Israel and Israelis to focus interest and anger their way. In this way they act like children seeking any kind of attention.
So expect them to keep trying different kinds of attacks, probably from the West Bank, like the bus bombing at the end of Pillar of Defense. (UPDATE: Yep, that's exactly what they are doing.)
