Howdy Nicolai; 1. The status quo can be maintained indefinitely. Nobody likes it, but when the Palestinians' military options are slowly being reduced to near zero, Israel doesn't seem to care too much about the Palestinians's bogus claims. As long as the Palestinians embrace the cult of martyrdom, it is unlikely that they will ever learn anything much less how to win. 2. There are no pre-'67 borders. They were armistice lines. If the Holy Land cannot accommodate both peoples, then it won't be the Israelis who will be moving. 3. You can take President Ahmadinejad's advice and file it in the nearest dumpster. "...do you see alternatives"? Plenty, but you won't like any of them. The most likely outcome is that the futuristic Islamic Republic of Palestine will consist of 92% of the West Bank and 100% of the Gaza Strip (provided that Hamastan can be reunited with the PA). I don't want to get into the other alternatives right now because I don't have the time to discuss them.
