Are there precedents for treaties which only come into force once approved by the legislature of the all involved nations?
As a counter example , the Paris Agreement was merely signed in as an Executive Order by President Obama and was never approved by Congress. As a result, President Trump was able to leave the Paris Agreement with a stroke of his pen, somewhat jeopardizing the future of the entire deal. A similar problem happened with the Iranian nuclear deal.
But are there precedents where negotiators take this into account and announce that the agreement will not come into force unless approved by the legislature? So i.e. the Paris Agreement would've been considered moot up until it was signed into law or (even better) voted in as an international treaty by 2/3 of the legislature, effectively making Obamas signature a mere stepping stone to the final treaty.
