Death to NATO

colombia doesn't love ukraine, there's a mix of factors like the other comrade says:

far-right indoctrination thinking about russia like "ussr"

past far-right governments giving crappy retirement and crappy salaries to soldiers but keeping the facade with the "our heroes" propaganda

lack of profitable options for a retired soldier: being a far-right paramilitary doing drug-trafficking, killing union leaders, leftist politicians and environmentalists in the country, or fighting as a mercenary abroad

Well, this is from my own investigation but there are three strong reasons(people could add their own as well):

• Money. NATO shills, through US funding, advertise big salaries to ex paramilitary soldiers, ex military, and ex police men. Those salaries are simply hire to whatever Colombian drug traffickers or even the gov't offer so these people take the bait. Example down below with 2.8k USD as salary for mercenary work.

• Fascist sympathizers(example in Spoiler). There is just a lot of fascists that have been trained by the USA from years of struggle with the guerrillas. Also, the US have plenty of bases in Colombia which will leave you wonder: Why does Colombia have so much land used to farm drugs? The answer is very similar to Afghanistan's US occupation years(good book on this is Seth Harp's The Fort Bragg Cartel).

• Strong influence from Ukrainian/American to form sympathy for fascists and dehumanization of Russians. This one is in great part due to US corporate media.

They don't. But the Colombian far right and Colombian cartels see an advantage in sending people over to receive military training in modern weaponry and combat experience.

Most of the mercs don't go there because they love Ukraine. They either do it for money, because they come from poor countries and the Kiev regime's international recruitment ads promise an easy way to make a lot of money. Or they do it because they have some sort of fascist ideological sympathy or a grudge against Russia, either generational or inculcated by the media's propaganda in their own countries.
