Our government is, indeed, a government by the women as are all the western democracies. Switzerland was the last to succumb but the rot is setting in even there. Our governments, whether socialist or conservative, depending on majority votes, continually move toward the feminist positions and the nanny state develops apace.
While on the other side of the world, due to forced abortions and the "one child per family" policy, China is developing a very masculine culture that grows more warlike as the sexual balance grows heavier at the masculine side. A nation of Men is more warlike, more aggressive, and will probably dominate at some time in the future. A feminine culture such as in the USA and in the European nations, will not even defend itself because it psychologically must rely on an outside force for that defence, on a larger entity- the UN which is, of course composed effectively of the US and the feminized Europeans.
The masculine Islamic cultures are not really a long term threat because they cannot develop the economic ability to do anything about conquest. They must rely on infiltration which will fail as a policy in the end because the women do understand about the dangerous outsiders and will likely close off the borders eventually.
Giving women the vote would seem to be the deathblow to Western Civilization, but it is not so easy as a single act, even that act. As economies advance and societies get rich the women have greater and greater influence because survival no longer requires that they remain at home and in the fields having babies annually. They become active players in the econmomy and itellectual equals with the men because the society is rich enough. Even without the formal vote, wealthy societies that have conquered most disease and infant moprtality will be feminized.
And then there is China. Chinese expansion and competition will become more robust as the masculinized culture itself gets richer. Ending "One Child" tomorrow will leave the world with 20-40 years of Chinese masculinity.
