Israeli Iron Dome system passes test

Strategy Page:

Israel had the first successful test of its Iron Dome anti-rocket system on July 15th. The system detected and shot down several BM-21 rockets. The Israelis expect to have the system in action, along the Gaza border, later this year. The manufacturer, Rafael, was offered a large bonus if they got the system working ahead of schedule. When Iron Dome was first proposed three years ago, it was to take five years (until 2012) to get it operational. In addition to the cash incentive, there's also the rockets still coming out of Gaza, and being stockpiled by Hezbollah in southern Lebanon.

Iron Dome uses two radars to quickly calculate the trajectory of the incoming rocket (Palestinian Kassams from Gaza, or Russian and Iranian designs favored by Hezbollah in Lebanon) and do nothing if the rocket trajectory indicates it is going to land in an uninhabited area. But if the computers predict a rocket coming down in an inhabited area, a $40,000 guided missile is fired to intercept the rocket. This makes the system cost-effective. That's because Hezbollah fired 4,000 rockets in 2006, and Palestinian terrorists in Gaza have fired over six thousand Kassam rockets in the past eight years, and the Israelis know where each of them landed. Over 90 percent of these rockets landed in uninhabited areas. Still, a thousand interceptor missiles would cost $40 million. But that would save over a hundred lives, and hundreds of injuries. A cheap price to pay, especially if you are one of the victims, or potential victims. Israel already has a radar system in place that gives some warning of approaching rockets. Iron Dome will use that system, in addition to another, more specialized radar in southern Israel.

...

There is more.

This is a system that Democrats in Congress would never approve for the US, but it will be a life saver for the Israelis and change the strategic calculus of its Arab and Iranian foes. Hopefully, we will learn enough from it to develop our own system.

Should Republicans go ahead and add Supreme Court Justices to head off Democrats

Washington Post: Some Democrats eye adding more justices to the Supreme Court to change its ideological bent The once-remote idea has gained the attention of liberals angered by the GOP push to remake the federal courts. Probably the easy way to defeat this court-packing scheme is for Trump to propose doing the same thing now.  It would lead to Democrat denunciations and claims that it would be wrong, thereby blowing up any attempt by them in the unfortunate event of Democrats winning a presidential election.

29 % of companies say they are unlikely to keep insurance after Obamacare

Conn Carroll: A new survey of 368 midsize to large companies found that 29% of them are considering terminating their active employee health care plans when Obamacare is full implemented in 2014. Only 71% of employers surveyed said they did not expect to drop their health coverage, while 20% said they did not know and 9% said they were planning to exit. The latest survey, conducted by Towers Watson, echoes an ealier survey by McKinsey & Co. finding that 30% of private-sector employers were planning to drop their employee health insurance coverage by 2014. When the Congressional Budget Office crunched Obamacare's spending numbers, they estimated that only 7% of employees currently covered by employer-sponsored plans would lose their plans. ... This means the cost of the health care fiasco will be hundreds of billions more than estimated by the CBO and Congressional Democrat. It is also clear that Obama's pledge that you could keep your health care plan if you wanted t
