ELI5: In WWII, they had war bond drives so the government could raise the money to pay for the war. Why doesn't the government need to do that anymore for deficit spending?

They don't need to. The US government has no problem borrowing money right now (plenty of people are happy to buy US government debt for really cheap) through its regular financial programs, so why create a whole new program when the current ones are doing the job just fine?

The US Dollar is the global reserve currency. It's basically the foundation of the way that global trade is structured. So lots of people/organizations/countries are interested in holding dollars/US debt. This wasn't the case before and during WWII, so it wasn't as easy for the US to borrow money as it is today.
