Nope. Not even close.

This is international law, which is a name used for a huge mess of international treaties. What is there to say? There is no international police. If you don't respect international law, there is nobody to compel you to do anything. In essentially every case, you're beyond the reach of the counter party to the treaty (especially in this case since the ICC has zero reach). This is true whether "you" refers to a person or a country.
Hell, there's even valid reasons this keeps happening like that the political situation sometimes changes far faster than treaties can be negotiated.
There were some truly exceptional times in history, like the ending of WW2, where everyone agreed on a few rules and some limited things happened, but that time is long gone. Most countries find the international order deeply unfair, especially the "you're not allowed to move any borders unless you're one of the original nuclear powers" part. Russia is allowed to attack ... Iran is not. The "non-aligned movement" is essentially aligned on a single point: they all want to start limited wars against one or multiple of their neighbors but would face total economic collapse or worse if they did that and the US responded. That is the last straw holding the UN treaties in existence, the only enforcement mechanism that has survived 80 years of UN disintegration.
And now Trump got elected and has been sighted near said last straw with scissors, asking for money, complaining the straw costs too much. But don't be fooled: there's a lot of shouting at Trump, but nobody working to strengthen the treaties with a few more straws. And while I hate Trump, you have to give him this one: if he cuts, he may be giving the start signal for WW3, but saying he's causing it, is absurd.
