To quote Wikipedia on the broken window fallacy: The money spent on the war effort (or peacetime defense spending), for example, is money that cannot be spent on food, clothing, health care, or other sectors of the economy. The stimulus felt in one sector of the economy comes at a direct – but hidden – cost (via foreclosed production possibilities) to other sectors.
A basic understanding of economics would be useful for you to have in this thread.
We are sending Ukraine something of value: cash, weapons, whatever. That value leaves the US and therefore cannot be used for something else, fired in defense of US interests, or used to deter threats to the taxpayer who bought it.
Your initial point that “it’s fine to send this value to Ukraine because now we get to spend more money” to replace it is ridiculous.
Some of the weapons sent have negative monetary value, as in they were to expire and this process of recycling would cost a lot of money. So you should be thanking Ukrainians for taking this burden on themselves without US having to pay for the rendered services. You don't sound thankful enough.
You're putting a lot of words in my mouth that I didn't say. And further, you're lying about what I actually said. Please consider having remotely honest discourse if you want to discuss something. I don't want to engage anymore with propagandists who can't even respond the points being made.
