Why Preparing Against Terrorist Chlorine Attacks Is Imperative

Posted in Terrorism with tags , , , , , , , , , , , , , , , , , , , , on 071110 by romeosierraecho

Chlorine is a nasty substance (E-Plan). It has many characteristics desirable for terrorists, since it:

  • Is lethal in small quantities (100 ppm)
  • Is readily available as it is used widely in water treatment and plastics production
  • Is processed, transported and stored with little or no security
  • Becomes airborne by simply puncturing the container
  • Doesn’t dissipate easily as gas, since it is heavier than air

Unlike conventional explosives exploiting its lethal force doesn’t require complex or expensive preparation – just puncturing the vessel or blowing a hole in it is enough to release a lethal chlorine cloud. And unlike specialized chemical or biological weapons, a terrorist doesn’t need to manufacture it as they can go directly to locations where it is used.

A worst-case scenario is created below to further highlight the need for immediate action, and to prevent and prepare for a chlorine terrorist attack. While knowing the threat level is important, it is also important to know how one can protect against such an attack, and to not overreact over the slim possibility of being affected.

Sanity Check On The European Missile Defence System Debate

Posted in Military, News with tags , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , on 071028 by romeosierraecho

US stirred the news in March when President Bush proposed a missile shield to be build and activated in 2011 in Czech Republic and Poland to protect Europe from Middle-Eastern missile threats (BBC) – Iran’s future nuclear capability being the obvious impetus. Russia’s response involved flexing its atrophied muscles and offering their own poor alternative solution. Yesterday, Putin went as far as using cold war language by comparing the proposed system to the Cuban Missile Crisis (Guardian).

The Russian “alternative” to the sites in Czech Republic and Poland was a proposal to put the site in Garbala (Qabala), Azerbaijan (MSNBC). The diplomatic manoeuvre sought to look for an alternative which would not counter Russia’s ICBMs, but would still protect Europe from Iranian threats. Both of these “problems” in the American proposal are easily countered:

  1. US proposal calls for 10 ground-based interceptor (GBI) missiles (FAS) along with the radar. This is clearly not enough to counter the Russian nuclear threat, considering they have literally thousands of warheads (Arms Control Association).

  2. While the site in Azerbaijan would be very close to the potential launch sites in Iran, that also means it is not the optimal location for interception and elimination of the threat. The missiles would fly away from the shield site, making intercepting harder. Also, most of Europe is outside the reach of even X-Band radar (FAS) – the type proposed to be used at the Czech site.

European missile defence shieldThe latter point is clarified in the adjacent map (also as Google Earth kml). The large red circle is a 6,000km range for a ballistic missile from Tabriz, Iran – a potential launch site. The red lines show potential non-military targets in central Europe. Open source information on Iran’s ballistic missile arsenal is sketchy, but it appears that Iran has or will have a platform capable of reaching most of Europe by the time they have the capacity to collect enough fissile material for a bomb. Iran’s Shahab-4 has a range of ~2,000km, and Shahab-6 which is in development will have a range of 6,000+km (FAS).

The green and blue circles are the sites in Czech Republic and Azerbaijan, with a 2,000km range with their X-band radars to be deployed. The ranges for the GBI have not been published, but old test reports suggest a range of at least the same as for the radar (FAS). The map shows that an Iranian missile would go out of range of the Azerbaijan-based radar about half-way to the target, making early identification and prompt interceptor launch even more critical than with the eastern European site.

US has claimed that the Russian counter-proposal would be a complementary solution, but it would not replace the eastern European solution. The analysis above supports that notion, and shows the poor justification behind the Russian counter-proposal.

Syria Clears Bombing Site In Record Time

Welcome to Sensible Intelligence!

Israel bombed something in northern Syria on September 6 (The Economist). What exactly Israel bombed has been a source of grand speculation in the world press ever since. Now it appears that the most likely target was a 5-megawatt nuclear reactor under construction, possibly of North Korean design. That reactor is “large enough to make about one nuclear weapon’s worth of plutonium each year,” according to The Institute For Science And International Security (ISIS *) analysis.

ISIS acquired DigitalGlobe and Spot Image imagery of the suspected bombing site, and compared the data in three briefs (1, 2, 3). The results were reported worldwide (New York Times, Washington Post, BBC News, Jerusalem Post).

The site is clearly visible in its pre-bombing state on Google Earth (kml 35°42’27.68″N 39°49’58.81″E) from Spot Image data from 2007. Also, the Yongbyon nuclear site in North Korea (GlobalSecurity) can be compared on Google Earth (kml 39°47’50.27″N 125°45’17.27″E – note cooling tower ~185m SSE from the coordinates).

Syria bombing site (source: Google Earth 071027, DigitalGlobe imagery taken 5-28 August, 2007)The Syrian site was in its infancy, as it only had two buildings plus the potential pump station on the river bank. Curiously, the long secondary building visible in the ISIS images dated August 10, 2007 does not exist in the Google Earth imagery (highlighted with a red circle in the image on the right). This suggests that the GE data is from earlier this year, and that the site was in active development prior to the bombing. Ogle Earth has created a high-resolution kml overlay which makes comparing the images easier.

Its efforts focus on stopping the spread of nuclear weapons, bringing about greater transparency of nuclear activities worldwide, and achieving deep reductions in nuclear arsenals.”
