Power of Attorney of Colonel John Butler for Robert Hamilton and Robert Addison, January 4,1797

John Butler (1728-1796) was originally from Connecticut but settled with his family in the Mohawk valley of New York around 1742. His father was a Captain in the British army and well acquainted with William Johnson (superintendent of Northern Indians). Butler impressed Johnson with his aptitude for Indian languages and diplomacy. He began to work with Johnson in 1755, and received several promotions in the department, until his apparent retirement in the early 1770s. At the onset of the Revolutionary War in 1775, Butler relocated to Canada to join the British forces, settling in Niagara. During the War, Butler was instrumental in maintaining the alliance with the Indians. After the War, Butler became prominent in local affairs in Niagara, but failed to secure any important offices when the province of Upper Canada was formed in 1792. In an effort to recoup some of the financial losses his family suffered during the War, Butler illegally attempted to supply trade goods to the Indian department with his son Andrew, his nephew Walter Butler Sheehan, and Samuel Street, a Niagara merchant.

Modeling short-range ballistic missile defense and Israel's Iron Dome system

This paper develops a model of short-range ballistic missile defense and uses it to study the performance of Israel’s Iron Dome system. The deterministic base model allows for inaccurate missiles, unsuccessful interceptions, and civil defense. Model enhancements consider the trade-offs in attacking the interception system, the difficulties faced by militants in assembling large salvos, and the effects of imperfect missile classification by the defender. A stochastic model is also developed. Analysis shows that system performance can be highly sensitive to the missile salvo size, and that systems with higher interception rates are more “fragile” when overloaded. The model is calibrated using publically available data about Iron Dome’s use during Operation Pillar of Defense in November 2012. If the systems performed as claimed, they saved Israel an estimated 1778 casualties and $80 million in property damage, and thereby made preemptive strikes on Gaza about 8 times less valuable to Israel. Gaza militants could have inflicted far more damage by grouping their rockets into large salvos, but this may have been difficult given Israel’s suppression efforts. Counter-battery fire by the militants is unlikely to be worthwhile unless they can obtain much more accurate missiles.
