How does Westboro Baptist Church support the idea that soldiers will go to hell?

I'm skeptical of the claim that they believe soldiers go to hell. At least, it needs a bit of nuance. They seem to believe American soldiers go to hell, but probably not soldiers generally.

I spent a bit of time searching their website and found an FAQ talking about why they have events at soldiers' funerals. Here's what it says:

Why do you preach at... soldiers' funerals?

To warn the people who are still living that unless they repent, they will likewise perish. When people go to funerals, it is one of the few times that they have sincere, sober thoughts of mortality, heaven, hell, eternity, etc., on their minds. It's the perfect time to warn them of things to come. It is a great kindness to remind people of the truth contained within God’s word of these sober, grave topics – the most important for any person to think of in their brief lives – while their minds are on such topics for that brief moment of sobriety...

As for funerals of fallen soldiers – when a nation rises up in pride against God, one of the ways that God punishes that nation is by killing her men of war. “She hath been proud against the LORD, against the Holy One of Israel. Therefore shall her young men fall in the streets, and all her men of war shall be cut off in that day, saith the LORD.” (Jeremiah 50:29-30). Soldiers’ funerals often become more of a ‘patriotic pep rally’ than they do anything else. Rather than ‘mourning’ the death of someone who willingly fought for a nation awash in sin at every level, those present at such occasions should rather mourn, deeply and with great shame, for their sins – as the same God who took the breath of life of those fallen will shortly take ours. What state of heart will you have when the Lord comes to take your breath of life? What of eternity and your never-dying soul? “What will ye do in the day of visitation?” (Isaiah 10:3).

So it looks like they have some bad exegesis and misunderstandings about what Jesus said regarding the dead burying their dead, but none of this indicates that they think all soldiers go to hell by virtue of being soldiers. Rather, they seem to think America is cursed for rising up against God like so many of the Old Testament cities and nations and that her soldiers are being struck down because of this.

If that were true, I would expect far more American casualties in the 20 years we've been at war since 9/11. Even counting suicides, which far outnumber KIA deaths, US soldiers only died at a rate of roughly 5 per day over the course of roughly 20 years. It's about 1 per day if we only count those KIA. That's not to downplay the loss of life, but 1 soldier dead per day is hardly a divine reckoning. God can kill a lot more soldiers than that.

I also found a video they produced called Thank God for Dead Soldiers. The introduction to this indicates to me that they are taking the erroneous view that God actively wills every event, good or evil, rather than distinguishing between the active and passive wills of God, as most orthodox Christian theologians would do. The narrator of this 2 minute video states that these soldiers who are going to fight in the middle east are seeking a "macho rush" and don't realize "that God is their enemy." I'm not certain if this is meant to imply she thinks God is on the side of Muslims - an odd view for fundamentalist Christians to take - or that He is punishing these soldiers for their prideful belief that they can just "go over there and push buttons and win."

After reviewing their own material, I don't think that they believe soldiers generally go to hell, but that soldiers willingly fighting in an unjust war for a corrupt nation that has made itself the enemy of God go to hell, and that they further believe that all American soldiers are culpable of willful participation in injustice via war.

The attitudes the woman describes the soldiers as having are major sins of pride (think they can "just go over there... and win"), greed (they are fighting for a paycheck and a nice benefits package (this is laughable)), and bloodlust (they are seeking a "macho rush"). Certainly these are damnable sins, and that is easily supported by scripture, and those who die without repenting of them probably go to hell. It seems they are making a hasty sweeping judgement of all American soldiers as being unrepentantly guilty of these sins, thus damned to hell.
