I don’t think true fusion bombs have ever been miniaturized, have they? The max yield I’ve seen for suitcase nukes is in the 10-15KT range.

That is the size expected, around 10KT.

The biggest problem is, multiple explosions at once, in various cities.

This isn't a suitcase bomb but it would certainly fit in a truck or a container. W-80 warhead (10-150Kt fusion weapon)

Another little blurb

The W47 was 18 inches in diameter and 47 inches long, and weighed 720 pounds in the Y1 model and 733 pounds in the Y2 model. The Y1 model had design yield of 600 kilotons and the Y2 model had a doubled design yield of 1.2 megatons.
