The only NATO country to be attacked is Poland by Ukraine. There is zero indication that Russia intends to invade any NATO country. The difficulties that the Russians are having dealing with just Ukraine lend themselves to the conclusion that they are unable to invade any other countries. It's a dangerous premise to suggest that WWIII should be risked based on a regional conflict in which the US has no direct interest. The US taxpayers have already paid THREE times the total annual Russian military budget to finance this war.
Do you ever ask yourself why the US always involves themselves in these endless conflicts and pays for them while other countries do little or nothing? Don't you find that odd? If Europe is at risk, why aren't they carrying the burden of this war instead of the US? How long are US taxpayers going to fund this war? Will it be like Afghanistan in which the military and politicians lied for decades about the progress being made to obtain billions of dollars only to have the entire situation fall apart within a week. You have no concern about the Ukrainians lying to try to bait the US and NATO into WWIII?
It is false to suggest that no other country are is doing it's share. From (from November 10, 2022 data):
https://www.statista.com/chart/27278/military-aid-to-ukraine-by-country/Yes, the U. S. has contributed far more than any other country. As is natural, since we have the world's biggest economy.
A better measure is:
Per cent of a nation's GDP, or "Gross Domestic Product"
which is, by country:
0.90 % Latvia
0.30 % Poland
0.25 % United States
0.10 % Great Britain
0.06 % Canada
0.03 % Germany
This may be a little misleading because this chart, for the U. S. shows military, financial and humanitarian aid, where I believe the figures for the other countries is just for military aid. So the total contribution, counting financial and humanitarian aid of the other countries is actually higher.
Germany's contribution being low is understandable, given their extreme dependence on energy supplies from Russia, more so than any other country. They arguably have enough to do providing heat for their homes. And their military needs to be beefed up a lot. Germany's military strength is at such a low level, they just don't have a lot of surplus they can immediately send. So much for putting one's faith in Russia's good will. Poland and Latvia are in stronger positions to help, partly because much of their military equipment is of the old Soviet style, more compatible with what Ukraine is mostly using in it's war.
And European countries, in far greater danger of direct invasion than the United States, need to start beefing up their own military, as well as sending aid to Ukraine.
It is surprising how much Poland and Latvia have contributed, given how poor those countries are, and the threat they face from Russia in the coming years. On the other hand, they are in danger of losing 100 % of their GDP if Russia overruns them so spending up to 0.9 % of aid for Ukraine is very penny foolish, but dollar wise.
And again, our military aid to Ukraine is under 10 per cent of what we spend each year on our own defense. Most of our defense expenditures over the years, does not go into doing something useful, like subtracting from Russia's offensive potential. It generally gets stored away and not used, or used in questionable wars, like in Iraq and Afghanistan.
This ten per cent sent to Ukraine is by far the most productive, dollar for dollar, military expenditures, we have made in the last 60 plus years. It directly subtracts from Russia's offensive capabilities. These expenditures do immediate good. Much of this expenditures is in military aid that we consider obsolete but which is very useful for the Ukrainians. Yes, most Stinger Missiles are gone, but our military stopped using them or making them immediately available for our troops years ago, because we now have better and more useful options now.
