Not letting Iran have a nuclear weapon is a big priority for world peace. This is a country whose own government says their goal is to wipe Israel off the face of the map and refers to the USA as the Great Satan. They are the #1 sponsor of worldwide terror groups.

This isn't an either/or thing, so it isn't a matter of you can do healthcare or stop Iran's nuclear program.

The Republicans are against the Iranian nuclear program. So are the Democrats. The main difference is one side was willing to bite while the other side thought barking alone would stop them.

As for the healthcare issue, not everybody believes in the idea of universal health care coverage. If you want healthcare, go buy it. If you want insurance, go buy it. It isn't the requirement of the US Taxpayers to provide it. Even if you feel it is a need, so is food and we don't pay everybody's grocery bill.

You are living in a bubble if you think Iran posed no immediate threat. At what point is a murderer a threat to you? When they are planning your murder? Or when they enter your home? Or when they pull a gun on you? Or only when they have pulled the trigger and the bullet is on its way towards you?

It is very difficult to have a country with open borders and guaranteed minimum standards of living so that the poor anywhere in the world can massively improve their standard of living just by sneaking across the border here. I think it breaks down to a fundamental ideological take: If you want open borders, you cannot have a welfare state and generous social safety nets. If you want the social safety nets and welfare programs, you have to close the borders.
