This will be my last reply to you because I don't think you are actually here for debate. Whenever you're confronted with counter arguments to your incorrect representations of history, politics and war you just yell "WHAT? ARE YOU IN FAVOUR OF DICTATORS AND MASS MURDERERS?" or something similar. Which doesn't engage the arguments raised at all and doesn't follow from those arguments either.
Have you considered that corporate capitalism is actually the problem? Resulting, quite recently, in shifts to authoritarian leaders in "democracies" like Bolsonara, Trump, Victor Orban, Mateusz Morawiecki and the destruction of the Hong Kong democracy. This has only been possible with monied interests being either complicit (HK, Trump, Bolsonara) or acquiescing to it. In HK all the parliamentary seats appointed by "business" are pro-China, because that's where the money is. And granted the US stopped being a democracy some time ago and is already a full-blown plutocracy. Reagan was probably the nail in that coffin.
As Daniel Kelemen described:
Elected autocrats tend to follow six steps: win elections; capture referees, such as courts and other independent bodies; attack or seize control of the media; demonize and undermine the opposition; change the rules of the game; and win new elections that are no longer free. — Kelemen
Each one of those "leaders" of "democratic" countries are following this playbook and are in essence autocratic. They are not qualified to spread democracy to begin with. The more important point though, is that democracies don't seem to be able to survive under the pressures of corporate capitalism. So you are willing to murder millions of people - there are after all only 72 democracies in the world - to implement a system that will destroy itself as long as we continue to pursue corporate capitalism.
The democracy index only measures the following though:
"Whether national elections are free and fair";
"The security of voters";
"The influence of foreign powers on government";
"The capability of the civil servants to implement policies". — Democracy Index
The first thing to note is that the countries higher on the list are welfare States with strong social and governmental institutions and strong
socialist political movements. And although all of them have their share of populist, authoritarian political players, those don't garner more than 20% support. If we want democracies to survive, they should be non-capitalist, social democracies.
The influence of big business is obvious. In HK 90% of
voters voted for pro-democracy MPs. A clear majority over the Chinese appointed MPs but because the business appointed MPs voted pro-China, voters got shafted.
The US it's obvious for local influence by aflluent Americans on policies (see
why the US is a plutocracy). And here's some conclusion with regard to influence by big corporations on foreign policy.
We can say that they have greater means and seem to use them to exert more influence than other firms, even big domestic ones. But are they more able to convert these means into success politically? Again our data cannot give a direct answer. But the direction of US foreign economic policy in the past decades suggests they have been very powerful. The lowering of trade barriers via the GATT/WTO and various preferential trade agreements, the opening of capital markets and signing of bilateral investment treaties and economic agreements with investment protections, and the harmonization of regulations in many areas in preferential trade agreements are all policies that the US government has pursued actively and ones that MNCs have championed. MNC preferences, versus those of purely domestic firms, seem to be very congruent with much of recent American foreign economic policy. Rodrik (2018) claims, for example, that preferential trade agreements are tools for MNCs: “Trade agreements are shaped largely by rent-seeking, self-interested behavior on the export side. Rather than rein in protectionists, they empower another set of special interests and politically well-connected firms, such as international banks, pharmaceutical companies, and multinational corporations” (as cited in Blanga-Gubbay, Conconi, and Parenti 2019, p. 4). — Kim Milner
Once this is fixed we can start thinking about spreading democracy.
