That might be technically true, but the F35 and F16 are both single engine aircraft and IIRC constitute the bulk of at least the US air force’s combat aircraft.
B2, F117, B52, P9, F22, F14, F18, C130, C17, C5, CH47, AH-64, SR71, U2, A10, and on and on just to give some recent examples.
There are a few single engine aircraft roles (including the F104), but they are not and have never been the bulk of active serving aircraft. It isn’t just ‘technically’ true.
Be that as it may, the workhorse combat aircraft of most NATO air forces and the USAF itself is the F-16, a single-engine fighter, and its nominal replacement, the F-35 is also single engine. You can try to make your point by comparing those vs the numbers of F-15s, F/A-18s, F-Fs, Rafales, Eurofighters and so on in service vs the F-16 and F-35, but bringing C130s and C17s into it is irrelevant, those are not "combat aircraft".
edit: ah but they are "military aircraft", sure. fine.
