convergence zone of the Eastern Hemisphere. A European power trying to dominate the Mediterranean or expand eastward, an eastern power trying to dominate the space between the Hindu Kush and the Mediterranean, a North African power moving toward the east, or a northern power moving south all must converge on the eastern coast of the Mediterranean and therefore on Israel. Of these, the European power and the eastern power must be the most concerned with Israel. For either, there is no choice but to secure it as an anchor.Internal GeopoliticsIsrael is geographically divided into three regions, which traditionally have produced three different types of people. Its coastal plain facilitates commerce, serving as the interface between eastern trade routes and the sea. It is the home of merchants and manufacturers, cosmopolitans not as cosmopolitan as Phoenicia or Lebanon, but cosmopolitan for Israel. The northeast is hill country, closest to the unruliness north of the Litani River and to the Syrian threat. It breeds farmers and warriors. The area south of Jerusalem is hard desert country, more conducive to herdsman and warriors than anything else. Jerusalem is where these three regions are balanced and governed.There are obviously deep differences built into Israel's geography and inhabitants, particularly between the herdsmen of the southern deserts and the northern hill dwellers. The coastal dwellers, rich but less warlike than the others, hold the balance or are the prize to be pursued. In the division of the original kingdom between Israel and Judea, we saw the alliance of the coast with the Galilee, while Jerusalem was held by the desert dwellers. The consequence of the division was that Israel in the north ultimately was conquered by Assyrians from the northeast, while Babylon was able to swallow Judea.Social divisions in Israel obviously do not have to follow geographical lines. However, over time, these divisions must manifest themselves. For example, the coastal plain is inherently more cosmopolitan than the rest of the country. The interests of its inhabitants lie more with trading partners in the Mediterranean and the rest of the world than with their countrymen. Their standard of living is higher, and their commitment to traditions is lower. Therefore, there is an inherent tension between their immediate interests and those of the Galileans, who live more precarious, warlike lives. Countries can be divided over lesser issues and when Israel is divided, it is vulnerable even to regional threats.We say "even" because geography dictates that regional threats are less menacing than might be expected. The fact that Israel would be outnumbered demographically should all its neighbors turn on it is less important than the fact that it has adequate buffers in most directions, that the ability of neighbors to coordinate an attack is minimal and that their appetite for such an attack is even less. The single threat that Israel faces from the northeast can readily be managed if the Israelis create a united front there. When Israel was overrun by a Damascus-based power, it was deeply divided internally.It is important to add one consideration to our discussion of buffers,
