Just 15 months after Israel sought to drastically reduce the rocket threat from Gaza in Operation Pillar of Defense, Hamas has substantially bolstered its capacity to fire on Jerusalem, Tel Aviv and the rest of central Israel.

The Gaza Strip’s Islamist rulers have invested heavily in producing their own M-75 rockets, with a range of 75 kilometers and more, and now have an arsenal of dozens of the rockets, The Times of Israel has learned. They will have dozens more by the end of this year.

This means that the next round of conflict with Gaza will be focused on central Israel, with the Israeli military braced to defend the heart of the country against unprecedented salvos of M-75s directed at Tel Aviv, the rest of central Israel, and Jerusalem.
