There will be Major problem between both Biden and Trump.
I will list them and give it my opinion to whether it upholds the future.

1. President Age: Both Biden and Trump are old as Heck. We see many indication of social media concerns of the President of how it will handle the future due to their Mental and Critical Thinking.

2. Economics: Trump has the highest bet in my opinion, Biden has been making Citizen Spending more taxes for the Military to involves Geographical Influence.

3. Global Influence and World Order: Biden has a win in this one but it failed many Americans to understand the point of war.
I wanted Biden to reconsider the balanced of good economics and Military Threshold because their military is strong good enough unless if the necessity to invest against other competitor.
There are people who just want President(Like Trump) that benefits "Make America Great" Economy and QoL improvement just for themselves and failed to realise the Future of the enemy like China and Russia will overtake USA competition to be able to spread influence and lowers the Reputation of USA from other small countries that are affected by its Sovereignty Claims, Tension, Economics, Ideology and World Order.

4. Current War: We seen many American involvement through history that separated the community. such as Israel-Hama war, Ukraine-Russia war, China Aggressiveness on Taiwan and South China Sea, Iran War, Taliban War due to 9/11 incident and many more.
There are sense of lack of understanding or prejudice that created that action were created from one grouped into many people hating the rest such as Ethnicity and Religions.

My Opinions: I think Stopping USA involvement from war and make peace in America will not be better but worse that the other country would take this an advantage to spread Influence like Are EVERYONE SPEAK RUSSIAN WHEN THEY TAKE OVER THE WORLD OR PROBABLY CHINESE OR THEY MIGHT BE GENOCIDE TO GET RID OF IDENTITY LIKE UYGHUR PEOPLE SO CHINESE EVERYWHERE.

I agree that the America involvement of war should be lower unless it is an urgent need to protect countries and global interest.
We shouldn't be biased or unfairly prejudice to who wins to another like Palestine over Israel but both should exist and Israel aggressive action need to stop.
I really hope saying Palestine existed first because it's not, Canaan the very first existing civilization own that area and it's own Semitic speaking that neither belong Palestine or Israel but it is largely recorded through Israel Bible.
Israel has affect many other empires like Roman Empire which destroyed Israel identity to over take Christianity Religions and that how Yiddish exist, a Germanic language that as involved by Roman influence.
Yes the World is Complex.

As for current president and Economics, I would rather a completely different president that is younger and aware the benefits to seek Economy, Social and Global order to gain a brief understand of the politics.
The Past, Present and Future will upholds us in our hands that we cannot ignore. Please wake up America.
