Is the situation in Ukraine an example of why the USA has the 2nd amendment?

A foreign invader came into their nation. The military was unable to completely repel them and the people are having to fight as well. I saw they are making home-made road block, molotov cocktails, and other things they made on the fly. The men are all getting conscripted into the military and they may never have fired a gun in their lives. This seems to be one of the reasons the US Founding Fathers created the 2nd Amendment…so the people would be able to defend themselves and even be of use in the event they were needed to “join” the military.
