If there is overwhelming evidence for a claim, it's absurd to smear it as "trope".
So when Nancy Pelosi says: "If the capital crumbles to the ground,one thing that will remain is our commitment to Israel"[0] that's because she has in fact dual loyalty, to dismiss that as "trope" is to dismiss & deny reality.
Some of "our" politicians work overtime for israel's interests and neglect their actual job and obligations towards America.
It's not at all a moot point and you're coming pretty close to a generic 'dual loyalties' trope.
