> To say that israel invests in defense is at least 1/4 untrue, since the US sends billions every year.

This is factually incorrect. The amount of money that the US gives Israel is completely and totally irrelevant to whether or not Israel also invests their own money in defense.

The fact that the US has a problem with foreign influence literally does not matter for the statement above.

To be clear, I don't agree with the GP's implied suggestion that Israel is more defensive than offensive, but making objectively incorrect statements is not a valid way to refute that.
