There were sanctions against Venezuela, but they were drops in the ocean regarding the country’s economic collapse. There is nobody marching up the continent because conservatives in the US supported sanctions against the criminal Marxist regime. They are marching because the criminal Marxist regime broke their country.
Oh, I agree Venezuela’s gov’t is likely the bigger factor, but, the sanctions were quite effective too. I see this result as the combination of 4 factors: Bad gov’t in Venezuela, the sanctions (justifiable, but a factor regardless), Mexico not stopping the illegals, and then the US basically waving illegals in. All 4 factors necessary to cause this result.
