Exact Answer: At Least 5 Years
The United States of America is the superpower that has dominated international politics for decades. The US military is one of the strongest globally, and it’s only a matter of time before another country challenges them.
America has no equal on earth in terms of raw military might and resources, but all nations have weaknesses that anyone can exploit with patience and cunning.
The comparison of America would be against other countries like China, Russia, and North Korea with its military might. Then, it can pull back and make a strong stand in the continental US.
How Long Would America Last Against The World?
| Type | Time |
| With all the might of military forces | 5 Years |
| If America faced internal problems | 2-4 years |
It would last at least 5 years against the world. America’s air force is the most formidable in the world. 14000 Airplanes are spread across America while also being among the most popular aircraft with militaries worldwide. So any country attacking America with missiles will be shot down by Stinger or Avenger missile crews. In short, America is bound to destroy anyone trying to infiltrate their lands as it has the world’s largest navy with ships displacing 3,415,893 tons.
Even the US coast guard can stomp the enemies if they get into the war giving the navy more solid support. This gives the rest of the countries a chance to fight their way from the land, but the Army and Marine corps with ballistic tanks are ready to fire at anyone crossing the limit. It is safe to note that America has the world’s most advanced tanks.
America can be conquered in a coordinated attack by one overpowering foe, such as the USSR or China. It isn’t easy to imagine how a single country could overtake Washington DC. Still, all countries in America owe allegiance to Washington and would have to relinquish their military assets for an attacking force. In contrast, American forces defended the capital leaving few resources left for fighting elsewhere in America.
So there are two ways that America falls: internally or externally. Internally, three things have to happen: First, New York falls; second, Washington is taken. Of course, this will result from bombings.
Why Would America Last So Long Against The World?
It can last so long because America has the world’s most powerful navy, airforce, and army. This makes it impossible for France or Russia to push through the lines by land as American soldiers will shoot down the rest with their protective gear.
Another powerful line of defense is nuclear weapons. Even if the enemies break the line, America can launch nuclear weapons as a last resort. It has the power to eradicate any advancing army from the seashores. Also, America has its armies stationed in countries like Britain, South Korea, Japan, Pakistan, Iraq, EU countries, and other nations which immediately occupy opposition.
It is quite difficult to imagine a military force going against America as the world does not stand a chance. Notwithstanding that, the country has 1.5 million square kilometers of arable lands. Overall, it is pretty good at putting up a powerful defense.
The United States has been a powerhouse-in-exile for many years now, and any country can’t discount its importance in international trade and transnational politics. However, no country can last for long without an economy, so it’s probably best to focus on the question of how to restore America’s economic might.
The British had a sizable advantage in naval forces, but they were also preoccupied with the rebellion in their other joint colonies on America’s eastern seaboard. The Americans considered this more important than fighting off attacks from outside forces because of decades of settlements encroaching into Native American territory and remaining relatively uncontested.
Conclusion
The US is one of the most powerful countries in the world. They have a strong military, advanced technology, and many other things that give them an edge over other nations. If any country had to go up against the whole world at once, it’s been done before, and it didn’t end well for America.
This can only work if the rest of the countries are on the same page because the US has the resources and infrastructure to hold indefinitely against the world. It has the military, air force, and navy with the capability to eradicate the neighbors effectively. Overall, America is behind an impenetrable wall.
