We must not fall into the trap of projecting our own morality onto the Soviet leaders. They do not share our aspirations, they are not constrained by our ethics, they always consider themselves exempt from the rules that bind other states.
I think you can grow your economy and at the same time do a better job of harnessing greenhouse gases. I don't think you can expect any American leader to wreck the economy, nor as an ally and a friend of America and a trading partner of America should you want us to wreck our economy.
And let me say this as a politician I can promise you this, political leaders will never take risks if the people do not push them to take some risks. You must create the change that you want to see.
