The short, concise answer to the above question is no. After all, nations are sovereign in and of themselves, and any justification for invading and bringing war upon another country must follow rules; nations that do not adhere to those laws have violated the law and are thus subject to sanctions.
Since it is a known fact that the United States in recent times has brought war upon many countries, though it prefers to use alternative words to war, during which it has not suffered from any international or United Nations sanctions, this would seem to suggest that this warfare is absolutely justified and therefore America is right in its actions. The real reason why the United States has seemingly become immune to being sanctioned really comes down to the fact that the United States is the sole empire of the world, and practical nations are not wont to get on its bad side. Additionally, there are those nations of importance that prefer the United States to take action and thus to suffer from any potential opprobrium should the perception be that America is conducting itself unjustly towards other nations, via that warfare.
So too, it needs to be understood that since American warfare operates whether it be the Republicans or the Democrats that are in charge of either the legislature or the executive office, the reality is quite obviously that there are hidden powers that are themselves deciding as to who, what, and when warfare is initiated by America. That hidden power in America is its military-industrial-technology complex, which is driven not just by empire-building and augmentation, so of, in pursuit of power and profit, but also because it has no choice but to see that America is bringing war against some enemy or enemies, because it is necessary for their business enterprise foundation.
Indeed, it just seems like a real shame that institutions such as the United Nations are, when it matters most, of no influence upon what does or does not occur in international affairs regarding warfare, in particular, when it comes to the United States. Additionally, even though the Constitution of the United States makes it quite clear that it is Congress that must authorize war, this has consistently been circumvented in the modern age. So then, those nations that get on the wrong side of America’s desires and interests have placed themselves in the unenviable position of having to suffer from America's vengeance and ire, without any real recourse, as the rule of law and heralded international institutions will do nothing of substance on their behalf.
All of the above signifies that America, while not having the right to invade any country of its choice for regime change, can still do exactly that, because there isn’t any one country or group of countries that will stand in its way, and some of the time, those other nations of import are quite satisfied to see such regime change, mainly in the hopes that there is profit in there, for them, as well.
