If only we acted that way. Our levels of support to Israel are disproportionate to the benefits we receive. For better or for worse we would in no way tolerate the Israeli level of diplomatic and political sabotage without such a strong pro-Israeli lobby. If it's a moral imperative, then fine, but I've never heard a convincing description of what we're actually getting from the Israelis to justify the rest of the relationship. Just "having a democracy in the Middle East" is not itself useful, especially when literally everyone in the neighborhood wants to kill them. If it weren't for the pro-Israeli lobby they'd be getting the Ukraine treatment, strong words of support, but otherwise they'd be on their own.
I think you can probably trace such realpolitik and statecraft back to Mesopotamia and beyond.
"But Israelis have bought our corruptible political system to the point where all our politicians fight each other to prove who is more of a "friend" to Israel. If the US where acting in its real best interest it would keep Israel at much more of an arm's length. In a way Israel is much more of a dangerous enemy to American democracy than Iran, Russia, China or any other country."
That's a lot more serious than dispassionately noting how one nation among many that has an influential lobby in the United States.
But one other point that is worth considering: American public opinion of Israel is generally around 60% positive, 30% neutral, and 10% negative (source: http://www.jewishvirtuallibrary.org/jsource/US-Israel/poally...). Is it particularly shocking that politicians go where the votes are? No conspiracy theory required.
"Stepped-up NSA eavesdropping revealed to the White House how Mr. Netanyahu and his advisers had leaked details of the U.S.-Iran negotiations—learned through Israeli spying operations—to undermine the talks; coordinated talking points with Jewish-American groups against the deal; and asked undecided lawmakers what it would take to win their votes, according to current and former officials familiar with the intercepts."
What a laugh. A Palestinian in Hebron whose family has been there for thousands of years gets no vote, whereas a Jew from Brooklyn who just got off a plane and steals his land does get a vote in the Knesset. This is a democracy? How deluded do you think we all are?
