I think all these perspectives are mistaken, to one degree or another.
It is true that God is sovereign over literally everything, including natural phenomena (Psalm 29:3; 115:3; Jeremiah 10:10). It is also true that national sin can bring national judgment, even among "heathen" nations (i.e. nations other than Israel; Genesis 15:16; Proverbs 14:34; Amos 1—2, etc. ad inf.).
However, I would not attach any such one-for-one significance to these calamities, lest I fall under the judgment incurred by Job's three "friends," who thought they could interpret every act of Providence — for others.
Here is one reason why I am reluctant: another Biblical principle is this, and you may make bank on it: the greater the privilege, the greater the responsibility (Amos 3:2; Luke 12:48; Romans 2:1-2).
I say that to say this: if any nations on earth today deserve complete eradication because of their deliberate, defiant and arrogant rejection of abundantly-available truth from God, America would have to be right at the top of the list.
So let's not point fingers. Instead, let's humble ourselves, repent, and get to faith-born work.
