That would clearly be in violation of international law. The same stands here.
The farmers agreed to the license at the start. It's over. They don't get to pick and choose.
It's not Monsanto's job alone to defend international law.
There is not international law. Sure there are treaties, as you said, but Argentina produces a ton of food. If the U.S. does anything to darastic it will starve or at least decemate the economy.
Point being, the U.S. can do very little. Argentina has to be willing to uphold those treaties on its own or it will lose business (which is the incentive to uphold those treaties).
The US is a net food exporter to the tune of thirty million tons per year. If Argentina decided not to sell food to the US it would have no effect whatsoever.
A lot of seeds are actually hybrids which don't breed true. You plant two varieties in the same field, detassel one, and use the seed next year as your hybrid crop. You cross (say) a big growing breed with a fast growing breed, and because the two parent strains were uniform, the children will be uniformly big and fast growing, but the grandchildren won't.
This is why most farmers nowadays prefer to buy their seed corn: it's better but a pain to produce (anyone here have a summer job detasseling corn?). I'm curious if the pirated Monsanto breeds have third generation degeneration.

Put $1-2 million together, knock out the terminator genes, profit. How are you going to sue? The plant is no longer they same biological entity Monsanto rights apply to.
Small farmers could never fund that sort of effort, and large industrialized farms would be sophisticated enough and have access to legal counsel to know better.
