Abba Eban coined the phrase to describe the 1949 cease-fire line, the Green Line. About 8 miles from the line to the sea at its narrowest, the cease-fire lines risk the country being cut in half. Military depth calls for holding the Jordan valley. The Golan is the high ground, and rocky, barren, lightly-populated terrain. Eastern Jerusalem had a Jewish majority as far back as the 1850s, till they were driven out in the Jordanian siege of 1949. Fedayeen attacks from the Jordanian West Bank, 1949-67, and Jordan's unnecessary attack on Israel in 1967, made seizing this area prudent. Jordan's relinquishment of claim in the 1980s implicitly acknowledges this. Trusting strangers to be nice sometimes seems okay. But not in this particular case, if you've read any of the history of recent decades.
