How missiles are changing the Middle East

On October 31st rebels in Yemen fired missiles that travelled more than 1,000km towards southern Israel. Israel’s Arrow ballistic-missile-defence system intercepted them. It was the first time that Arrow had taken out a surface-to-surface missile, and the first time during combat in any war that missiles had been intercepted in space, according to Israeli officials. The Yemeni missiles probably travelled further than any ballistic missile launched during a war. How might advances in missile change the war in Gaza?
