Biden administration thinks Netanyahu may not last politically

It seems you are the one who doesn't understand the term. There's a very specific definition for it established by the UN: https://www.un.org/en/genocideprevention/genocide.shtml

Namely:

In the present Convention, genocide means any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such:

Killing members of the group;

Causing serious bodily or mental harm to members of the group;

Deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part;

Imposing measures intended to prevent births within the group;

Forcibly transferring children of the group to another group

Nowhere does it say every member of the population needs to be murdered. And Israel is very clearly checking the first three boxes at the very least.
