Your reckless use, of the term "enemy", clearly reveals your lack of understanding of international relations. As Ren tried to educate you, the diplomatic status between any two nations, at any given time, is either in a state-of-peace or in a state-of-war. Since there is no in-between, there can be no official "enemies", during a state-of-peace. For example, you typically can't do business or take a vacation in a so-called "enemy nation", during a time-of-war.
Currently, the diplomatic relations between the US empire, Russia, China, and Iran are all in a state-of-peace. Hence, being "strategic competitors", as Ren pointed out, is a very accurate way to describe the legal relationship, among those nations. In the case of the DPRK and the ROK, they are still in a state of war, since there was no peace treaty, to officially end the Korean War, that started in the last century. Hence, it would be legally accurate to say the DPRK and the ROK are still official "enemies" of each other.
Consequently, when politicians throw out the term "enemies" or "cold war", during a state-of-peace, that is their common propagandistic way to sway the masses to go to war, with the demonized nation, that may not necessarily be in the best interests, of its own people.
Please understand, his/her/their use of the English language is at a 3rd grade level. It assumes the definitions of words based solely on the context in which it first encountered the word.
Hillary said the biggest enemy to the US is the GOP. That's the definition it retained. Enemies are political constructs, not actual military threats. Russia "hacked" the 2016 election and made Trump President over Clinton. That's why they are the #1 enemy to the US.
In pursuit of resources and ideological furtherance, there are those we can label as adversaries, but that's far from "enemies." In a courtroom, the opposing parties are adversaries. They have opposing opinions and outcomes they are seeking, but that doesn't make their adversaries enemies.
Same is true in almost all aspects of life. On eBay, the people you're competing against to buy that rare Miss Piggy calendar are not your enemies, nor are the people driving up the price of Game Stop on the stock market.
Countries that are looking out for their own best interests rather than trying to make sure the US gets a fair deal are our competition, not enemies. Only when they are actively pursuing a military advantage over the US with the intention of using the threat of attack as leverage do they become enemies.
Of course, once anyone attacks, they are by definition our enemy, whether it's a country, the Taliban, Al-Quaeda, ISIS or the drug cartels. Simply playing "the game" of international relations doesn't make one an enemy. Trump proved how wrong it is to view anyone who isn't an ally as an enemy. He pushed past that and extended his hand to N. Korea and many Middle Eastern countries. This "feud" attitude of the Swamp needs to stop. I think that's one YUUUGE reason Trump was ousted. The establishment can't have peace break out globally. Where would all the money for military weapons come from?
