When I post on Atlas, that's expressing an opinion.
When the Senate Majority Leader of the United States makes a statement of this nature, and the President publicly agrees with him, that's more than "expressing an opinion". That's sending a message demanding a nation comply with a demand, with the implied threat of withdrawn support. Israel isn't China; it's a democracy, it has a right to exist, it has the right to defend itself, and it has the right to hold elections according to its own laws.
And we have a right to place conditions on the money that we send to other countries.
Don't like that? Fine, vote for someone else.
But to call this "interreference in Israeli elections" is just comical.
