We're approaching 8 million people: ten times the population in 1948, but still one of the world's smaller countries, not that you'd know it from all the noise about us.
Yad Vashem generally estimates the number of Jews murdered in the Shoah as close to 5.8 million. The number of Jews in Israel today is 5,837,000. Most of the 322,000 non-Jewish immigrants are culturally Jewish, and their definition has more to do with the politics of religion than with reality.
For a demonstration of how committed Israelis are to their national project, I recommend Alex Stein's blogpost yesterday. Alex is decidedly to the left of most of us, but not in a loony way. He's description of Israel and his feelings about it are easily echoed by almost all of us, and the disagreements we'd have with him are much less important than the agreement.
I posted my own thoughts on the matter in a concise way on Independence Day three years ago; the words are exactly right today still. Israel's First Century.
