Nothing in ISDS stops the state from leaving the treaty and nationalizing anything it wants.  The state and people are still supreme.  What they can&#x27;t do is join a free trade treaty, &quot;trick&quot; companies into investing, and then expropriate assets while still enjoying the benefits of free trade.<p>The problem with TPP is the ISDS goes far beyond these simple goals (the treaty has been &quot;commandeered by corporations&quot;, if you like).<p>But for simple, limited protection of assets in foreign countries, it&#x27;s a good thing, encouraging inward investment.
