America has wronged the whole of humanity with their imperial expansionist interventionist genocidal foreign policies, it's illegal wars, it's destruction of democracy, it's disgusting use of propaganda, it's destruction of the legal system and justice, it's promotion of greed and immorality, it's lust for power and wealth at the expense of the disenfranchised and weak, it's complete disregard for human rights, it's stark hypocrisy, it's lack of compassion, empathy or regard for those they kill, rape and generally trample all over for reasons that can only be regarded as sociopathic, it's promotion of the elites and vilification of the poor, it's introduction of mainstream terrorism and fear to implement fascist polices and to top it all off it's overt covering up of it's atrocities by silencing whistle blowers and using the media to misinform and distract the public from the important issues and cover up there crimes. Australians hate America, it's just our weak as piss politicians who have become puppets in Americas attempt to take over the world. America has exported nothing but terror, hopelessness, fear, lies, propaganda and trash TV. Fuck America.
If you're confused by these two little words, you've come to the right place. (Not that there aren't other right places.)

It's is a contraction for it is or it has.
Its is a possessive pronoun meaning, more or less, of it or belonging to it.
And there is absolutely, positively, no such word as its'.
A simple test
If you can replace it[']s in your sentence with it is or it has, then your word is it's; otherwise, your word is its.
Another test
Its is the neuter version of his and her. Try plugging her into your sentence where you think its belongs. If the sentence still works grammatically (if not logically) then your word is indeed its.
Examples
It's been good to know you. Contraction: it has
It's a bird! It's a plane! Contraction: it is
The dodo bird is known for its inability to fly. Possessive pronoun: its inability = the dodo bird's inability
HTH.
