You can't define whole disciplines of science to agree with random constraints that you invented. Instead, the purpose of disciplines of science is t… - Luboš Motl

Perturbatively, fundamental strings are more fundamental than branes or any other objects. In that old-fashioned description, D-branes are "solitons" — configurations of classical fields that arise from the closed strings. They are analogous to magnetic monopoles — which may also be written as classical configurations of the "more fundamental fields" in field theory. In a similar way, D-branes' masses diverge for 𝑔→0. Non-perturbatively, D-branes and other branes are equally fundamental as strings. In fact, when 𝑔 is sent to infinity, some D-branes may become the lightest objects — usually strings of a dual (S-dual) theory. When we include very strongly coupled regimes (high values of the string coupling constant 𝑔), there is a brane democracy.

Some extreme optimists argue that North Koreans won't know how to mount the bombs on their missiles. Maybe, they have completed the H-bomb but haven't invented the screwdrivers and ropes yet.

According to polls, a majority (around 60+ percent) opposes the radar base. But it's not necessarily the sensible part of the Czech population. The demonstrations against the base are usually organized by communists, Islamists, and "peaceful feminists" (which is fortunately not a numerous group).
