Does anyone else feel like the tiberium wars (in universe) were way too short

So putting aside the first tiberium war which take place over roughly three years, the second and 3rd ones only took place over the course of just a few months. At least the 3rd tib war has the excuse that kane was just using the war to summon the scrin but still it sorta takes me out of the universe knowing how short the wars are given their scale
