Adding solar panels to a military base is easy to do, but does nothing to tackle the main challenge, which is fossil fuel consumption by military jets, ships and tanks. For now, there is no alternative, green fuel that can be produced at the scale needed and without triggering unacceptable social and environmental consequences
Yes, all kinds of statements are sort of true even if absurd. E.g. CCCP could defuse the South Sea situation by stopping resistance and finally capitulating to the Republic of China (also known as Taiwan).
Like you say, absurd. China has no reason to stop its resistance to imperial conquest without any fight.
