This is more out of curiosity than anything...But as far as I know Eritrea was the only country that made no attempt to vaccinate their population. Even North Korea did so. So effectively the whole planet did it. From the most left wing to the most right. From the most democratic to the least. Every government. Every national medical authority. They all said 'We need to do this.'
Why do you honestly think they did?
It's not quite that simple.
The US took a unilateral approach to vaccination. US health authorities said (and still say) that anyone over the age of 6 months needs a COVID vaccine. Other countries took a more nuanced approach.
Consider Denmark. One year ago, the Director of the Danish Health Authority said this.
In retrospect, we did not get much out of the expansion of the vaccination program for children when it comes to epidemic control. But it is seen in hindsight.
Also consider this study, which shows that booster doses in college age students likely resulted in a
net harm.
Booster mandates in young adults are expected to cause a net harm: per COVID-19 hospitalisation prevented, we anticipate at least 18.5 serious adverse events from mRNA vaccines, including 1.5–4.6 booster-associated myopericarditis cases in males (typically requiring hospitalisation). We also anticipate 1430–4626 cases of grade ≥3 reactogenicity interfering with daily activities (although typically not requiring hospitalisation).
And let's not forget the resignation of the top two vaccine regulators at the FDA in protest of pushing boosters on everyone without sufficient data. They published this paper in The Lancet.
Thus, any decisions about the need for boosting or timing of boosting should be based on careful analyses of adequately controlled clinical or epidemiological data, or both, indicating a persistent and meaningful reduction in severe disease, with a benefit–risk evaluation that considers the number of severe cases that boosting would be expected to prevent, along with evidence about whether a specific boosting regimen is likely to be safe and effective against currently circulating variants. As more information becomes available, it may first provide evidence that boosting is needed in some subpopulations. However, these high-stakes decisions should be based on peer-reviewed and publicly available data and robust international scientific discussion.
A new wave of COVID-19 cases caused by the highly transmissible delta variant is exacerbating the worldwide public health crisis, and has led to consideration of the potential need for, and optimal timing of, booster doses for vaccinated populations.1 Although the idea of further reducing the...

Way back in January 2008, the ACLU published their own pandemic preparedness plan, which said this.
American history contains vivid reminders that grafting the values of law enforcement and national security onto public health is both ineffective and dangerous. Too often, fears aroused by disease and epidemics have justified abuses of state power. Highly discriminatory and forcible vaccination and quarantine measures adopted in response to outbreaks of the plague and smallpox over the past century have consistently accelerated rather than slowed the spread of disease, while fomenting public distrust and, in some cases, riots.
So your attempt to paint a black and white picture that pretends everyone said "we need to do this" is false. Other countries have MUCH more nuanced vaccination programs than the US and always have. That was always wise. It isn't exactly rocket science to understand that the medical interventions you take for an 80-year old woman in a nursing home may not provide the same benefit to a 20-year old male athlete at the top of his form.
So to answer your question, we have to first acknowledge that not everyone did the same thing. As to why they all did it? Fear. Uncertainty. The need to "do something". Overstating vaccine benefits while all but ignoring any potential harms.
I believe that vaccines provided a benefit to those at high risk who had never had COVID. To those who had been infected and recovered, and to those young, healthy people that COVID never posed a significant risk to, it was foolish to mandate them to be vaccinated. All it did was enrich Pfizer and Moderna while simultaneously violating trust, exactly as the ACLU said it would back in 2008. Have you seen that vaccine uptake is down across the board? It's because the CDC is pretending like the COVID vaccine is just as important to a 6-month old baby as the measles vaccine is. But most people know that's nonsense, and now they are questioning the utility of vaccines that DO have long-term safety and efficacy data.
Trust has been violated, and trust is paramount to public health. The people that pushed for indiscriminate vaccine mandates now own the fallout of depressed vaccination rates and the overall loss of trust in public health.
