We already spend enough to provide gold-plated healthcare to every single American.
We spend more than any other country on earth. ($4.3 trillion in total, ~$800 billion in annual federal spending alone)
Per-capita we spend the most but our systems suck.

If that 1% was redirected, hell, if every single dollar of the defense budget was completely transferred into healthcare, it wouldn't make a difference.
The insurance and pharmaceutical companies would gobble it all up.
There is more than enough money already.
Increasing spending from $4,300 billion to $4,368 billion won't fix anything.
The only way to improve our systems here at home is to improve them.
Same goes for education and social security.
The only nation that spends more on education per-capita is Luxembourg and they don't count because they are the size of a postage stamp. If we completely zeroed-out ALL defense and Ukraine spending nothing would change, the system would soak up the money with no net effect.
In terms of social welfare spending the United States spends the exact same per-capita as most of its peers. We are right in between Germany and Italy in terms of spending. Same as above, the broken systems we run would just soak up the money with no effect.
That $68 billion is having a huge impact in Ukraine, though.
edit: Think of it another way. $68 billion is about $200 per American. That isn't even enough to cover the cost of an annual checkup with a physician assistant at a clinic, when billed to insurance. (my last one was billed at ~$500 to Blue Cross with an out of pocket cost of $85)
If we zeroed out Ukraine aid and sent everyone a check that could only be used for healthcare, that would be about enough to get your blood pressure checked by a nurse-- and practically nothing else.
