Israel is a player, but not bigger than the banks, THEY are number one! Check out the history of, say, Deutsche bank. Older than most governments), and much wealthier than most of them, too. Israel does have their own very powerful “banking families” of course, it’s an international interest, not national.

I don’t think the banking families are concerned about, say, the Israeli-Palestinian conflict. They will sell to everyone involved, and make sure the winner is financed with many loans from the IMF or elsewhere.

Media? Yeah, US media is probably their biggest international ally after the US government, I think. Not an expert, new information always desired.
