Did The Church take a stand in the US against no fault divorce laws? I've never read or heard a trad priest condemn them in a sermon like I have other laws. I have heard it from Protestants.  

The so-called "no-fault divorce" laws began to be passed (the first one being in 1969 in California) around the same time as Vatican II was being implemented so there was probably no specific official stand by the Catholic Church as she began to crash into the New Religion.  But to defend the prelates of the time, these laws were simply a new and specific type of divorce which the Catholic Church has always taught may, for extremely grave reasons, may be necessary.  It is not the divorce itself that, in all cases, are evil and must always be avoided; it is the concept that one has the right to remarry a new spouse after such a divorce that the Church cannot condone.

I was alive and sentient at the time and I do not recall ever hearing what poche says above.  I simply to not remember anything being said about no-fault divorces at all (though I am sure someone will be able to find newspaper and magazine articles to prove that something was said somewhere; I simply don't have any memory of anything being said in Seattle where I was at the time).  The Church was roiling in other problems such as the problem of contraception, the early stages of abortion legalization in some locations in the United States (Washington State legalized abortion around 1970), the imposition of the Novus Ordo upon an unwilling faithful, the wholesale abandonment of the convents by religious sisters and of the priesthood by so many priests, etc.

Frankly, worrying about "no-fault divorce laws" in particular as opposed to the laws permitting divorce and remarriage in general is sort of like worrying about "partial-birth abortion" in particular as opposed to abortion and contraception in general.  In American politics (anyway) it is a sad state of affairs that people who would never condemn contraception and fully accept the so-called "right" to abortion" are considered "pro-life" if they say that they are against "partial-birth abortion".  Consider that this was the political position of every "Catholic" Republican candidate for the presidency in the last election cycle.
