Signs of Witness:
' Israel has tightened security at its airports, seaports and border crossings-increasing both technological surveillance as well as information gathering efforts -in order to thwart attempts at smuggling radioactive materials into the country. These materials could potentially be used in the production of a “dirty bomb” that could be detonated within Israel.
A “dirty bomb”, which is essentially a low grade nuclear weapon, is far less lethal than an atomic bomb, but can still lead to massive casualties and injuries should it be employed. It basically consists of an ordinary explosive “laced” with radioactive materials. When detonated, these nuclear materials then emit dangerous levels of radiation, which can quickly spread across a rather large area. As previously noted, Israel is growing increasingly vigilant of a possible ‘dirty bomb’ attack. Supervision at seaports is at an all time high, and new detectors have been put in place to identify nuclear materials hidden in containers and freight cargo.
Moreover, heightened security has been instituted at sensitive sites, such at the nuclear waste site in southern Israel, (emphasis mine) in order to prevent theft and smuggling of radioactive materials.
The United States instituted similar heightened security measures at its borders crossings and sea ports several months ago, following repeated security alerts. Radiation detection devices were placed along major access points into Manhattan, including bridges and tunnels. '
Consider this - both Israel and US are nuclear powers (even if the former won't admit it). Border restrictions won't stop fissionables and other hot metals already within their borders.
This sounds a lot like a warm-up to something bad. Hope I'm wrong.
