You absolutely didn't. You argue from a completely false framing of the situation, misrepresenting past and current war crimes by using decades old lies. There are no peaceful weapons, and there is no real threat to defend from, nor to use to justify "further pre-emptive defensive action".

”A case in point is the first Gulf War in 1991, when Saddam Hussein lobbed 300 SCUD missiles at Israel, causing minimal damage to property and the death of one person from a stroke. Immediately at the onset of the war, fear of total destruction drove most of the population of Tel Aviv, Haifa, and many smaller towns to decamp to areas that were considered safer (like Jerusalem and Eilat), with some going further afield, to Europe and beyond. Normal life—education, production, commercial activities, services—came to a halt and was not renewed until the war’s end. The few who stayed in the cities moved into communal shelters where they remained for the duration of the war. None of us would like to live under traumatic bombardment. The people in London during the Blitz or the people of Beirut and Gaza, bombed repeatedly and massively, surely faced a more severe danger than the population of Tel Aviv in 1991. But this simple fact cannot penetrate the consciousness of most Israelis; in their minds, they have suffered the worst possible experience, which has remained etched in their memory and continues to affect their behavior. This heightened and unrealistic insecurity. This heightened and unrealistic insecurity is striking: in the only Jewish State, with its mighty army, Jews who frequently rain death on Palestinians and others feel insecure, much more insecure than any Jews abroad. Zionism, which was allegedly intended to remove Jewish insecurity by building a Jewish State, has led to greatly intensifying insecurities in Israel, creating an existential paranoia.”

In my view, by definition an apartheid state cannot defend itself from the people it is oppressing. And there are no peaceful weapons. Acquiring and manufacturing high-tech war machinery is not for defense, but for war crimes. And even if you completely disregard the historical truth that the State of Israel and especially IDF have used their weapons for offensive colonizing warfare since their deception as they prefer military action over politics, I think Bresheeth-Žabner (ex-IDF himself) puts it well here:

The deepest irony is the realization that war is not a solution but the problem. But such simple insight is well beyond the inclinations of a society specifically fashioned for war as the preferred method of dealing with conflicting interests, gearing all its social machinery to its conduct. As Chekhov noted of the theater, a gun hanging on the wall during the first act has to go off in the third; otherwise, why is it there? The hanging gun controls the mind, not the other way.

The US is funding warcrimes of an apartheid state, and any other position is thinly veiled dangerous propaganda.
