It is.
You're shameless in your support of a convicted spy who betrayed the U.S.
And here's why: an American might be shameless if he supported spying against the US (given that all the facts were on the table and all that kind of thing), but a foreign government? What you're in effect demanding is that the Israeli government live by American interest. That is not the case, regardless the fact that many people seem to have some notion that the US actually owns Israel. Israel is another state, looking out for its own interests.
You don't know how much I agree with you on this. Israel is a foreign state, and we don't own it; we don't owe it, either. The U.S. looks out for #1, too, which is the United States. The U.S. and Israel have many interests in common, but they do diverge at times. The U.S. is looking it for its own interests as well. Pollard served the interests of a foreign country, not the U.S.; hence, he's going to die in his U.S. prison cell.
