U.S. DST nationwide would be idiotic; allow for each state/town/city to select their own UTC offset as long as it is to the nearest whole hour to reduce complications (eg. -4,-5,-6,-7,-8,-9,-10…etc.)
As for Israel, they should remain on UTC+3 all year… Hashem practically placed Eretz Yisroel in this location (with the perfect latitude and longitude) for this time zone.
