It's not that simple, there are other people also bribing American politicians with opposing stances/objectives (Gulf countries, for example), or else Bibi wouldn't have had to fly personally to meet with Trump and try to convince him like 6 times in the span of a year, risking arrest (for reference, I think Bibi only did it once when Biden was in office). In the end, the blame lies within America, because if the leaders were even slightly moral, or if the people cared even a little bit about politics (in general, I know many American Lemmings care), this shit wouldn't happen.
