Apparently not. The conservatives think that spending 1% of the defense budget helping mothers will somehow bankrupt the country. I kid you not.
You shall not kill is the commandment of God.
God did not make an exception that said "Unless you want to carve a nation out of land", or "Unless you need to kill in order to establish your rulership over people."
World War II was just, insofar as we were attacked. The way we fought it, with mass bombings of civilians, was not, but the cause itself was just.
By contrast, the Revolutionary War, the War of 1812, the Indian Wars, the Spanish-American War and the Iraq war were unjust.
The Vietnam war was not fought justly.
Since 1960, we have added trillions to the national debt fighting a series of unjust wars, and losing them to boot. We are behaving as an imperial nation, pursuing power for economic and power's sake, and killing people all over the world. These killings are not in fact in self-defense, and the "collateral damage" of innocent people is murder, because we have no business launching into these wars in the first place.
Nuclear weapons keep the peace, but huge conventional forces have been a temptation for us since the end of the Cold War. Instead of using the outbreak of peace with Russia as the opportunity to beat our swords into ploughshares and end the mad spending on the means of warfare, we doubled down to lap our former adversaries and possess armed forces stronger (for the moment) than the rest of the world combined.
And for what? The Russians and Chinese (and French and British) have sufficient nuclear arsenals that we could not invade them even if we wanted to. There was, and there still is, no credible military threat. Islamic radicalism is a real threat, but that cannot be dealt with by armies. In fact, using armies to squash ants has only inflamed the situation, making it worse and worse.
For us to have the sort of social safety net and human development structure we require now, and certainly we WOULD require if we stopped murdering babies, we have to remember that "You shall not kill', besides meaning that we can't murder babies for convenience, also means that we can't murder foreigners either simply because they are our adversaries. We need to slash the armed forces substantially, bring them home from the lost forever wars, put what we still keep on the Southern Border (forget the wall, use the army), and save trillions over time. Some of those trillions balance the budget. Some of them pay down debt. And some of them will go to proper, robust human capital improvement programs.
Of course this means completely giving up dreams of hegemony and empire. And it means accepting the necessary role of government in providing a social safety net and human capital improvements.
And that is a lot to demand of the American Right, who love the military and hate government. It is a price we have to pay to save the babies. The Left, for their part, have to give up on killing babies. They never will, so they will have to be shouted down by superior numbers and "oppressed" (in their eyes) by laws against abortion they do not accept.
