Maybe it's time to cross the line. Seems we the only ones expected to respect it

none of them did that

none of them did that? lol. okay let's go down the list:
nato expansionism since the end of world war 2 plus zelenskys terrorism caused russia to invade ukraine.
putin would've invaded regardless however, as his major goal is to reform the Ussr. plus he's murders his political opponents, plus they run dis and mis info campaigns worldwide which is partially why rt is always in trouble. also, all nations do this and all of them are spying on everyone all the time. literally.
china is constantly violating maritime laws and harrasing the phillipines and does not respect Taiwanese nor Tibetan sovereignty.
in south africa right now, christians are being beheaded by muslims.
isreal is the defacto ruler of the us, and blackrock is their de facto ruler. and using that relationship to commit genocide.
palestine/hamas is constantly terrorizing isreal, and the middle east in general does nothing about Islamic terrorism.
saudi arabia, their prince murdered jamall kashogii, and american journalist who still has not received justice.
dubai is built on stealing resources from other countries and slave labor as well. its an immoral shithole built by immoral shitheads.
most uk towns are now ran by muslims, and their federal government is sympathetic to the muslims and not the inhabitants.
every country including usa is numerous of various war crimes, every country defanged the world court the hague by essentially threatening to invade it if anyone gets prosecuted.
the un lets china run amok on their committees even though china is the worst human rights violator only second to north korea.
and the list goes on and on of how red lines are a myth, everyone crosses them, and then tells everyone else not to cross them. the hypocrisy of nations.
also, the elites in every single country, every single one, are involved in a satanic pedophilia cult. not one, not some, ALL.
the pope could end poverty with the wealth of the vatican right now. does nothing.
the catholics would rather pay off victims and shuffle their pedophiles around rather than prosecute them and make examples.
you want more examples?

My brother, are you tweakin?

I ain't your brother and all the historical evidence for all I said is there to be seen. All ya gotta do is read a few history books.

Like which ones? Trust me, I've read my fair share of them, and half of this shit I've never heard of talked about seriously

While it may seem like the United States, China, Palestine, Israel, Ukraine, United Nations, NATO, and numerous other countries are constantly violating international laws, it is crucial to highlight that they did not do any of what you said. The UN and other countries telling us not to cross red lines while the aforementioned countries engaged in actions contrary to international laws is simply not true. Each of these entities and countries operate within international legal frameworks and strive to maintain diplomatic relationships. It is essential to avoid assuming and spreading misinformation about these countries' conduct without valid evidence or thorough analysis. Therefore, it is important to fact-check claims before attributing violations of international law to any of these entities or countries, especially when it comes to such sensitive geopolitical matters.
