I'm not convinced that the US government is more broken than the others you list.
Most people killed by a government are killed not by police forces, but rather by armies, navies and air forces. And if you live in or near the US you have a lower chance of being killed in a war than if you live in or near Europe because although the US starts more small wars, it starts fewer big wars, and most people killed in war are killed in big wars.
Europe has started fewer wars and killed fewer people since 1945 than the US has, and this is a sign that Europe is safer for the average resident or neighbor than the US is, but that sign is more than cancelled out by Europe's record (and Japan's record) before 1945.
Over the centuries, most prolonged rivalries and most expensive arms races between European nations ended in a war. In contrast, the intense prolonged rivalry and extremely expensive arms race between the US and the USSR did not end in a war -- at least not a war in which the most lethal available weapons were used or in which civilians were targeted to the extent that civilians were targeted by European and Japanese governments during WW II. Surely, the USSR's government deserves some of the credit for that surprisingly good outcome, but so does the US government.
And if you want to claim that the US did not have to participate in the intense prolonged rivalry and extremely expensive arms race -- if you want to argue that the fact that it did is a sign that the US is badly governed, you have to face the fact that if it had not participated, all of Europe would've been overrun by the USSR. There was far less political will in Western Europe to prepare for yet another war than would've been necessary to resist an invasion from the USSR if the US hadn't paid for most of the preparations.
I do not conclude from this analysis that the US government is better than most governments -- only that it is not clear to me that it is definitely worse. And I think it is a mistake to draw a boundary at 1945 and claim that anything that happened before then was too long ago to have any bearing on the question of which of today's governments are better.
