[MBB1984]

There are several ways government can do to strengthen marriage (and I am recommending state government not federal). First, they can make divorce more difficult. Second they can punish adultery and actions that contribute to the destruction of marriage. Third, they can provide more effective punishments for those who don't provide adequately for their spouse and children. Fourth, they can punish those who contribute to illegitimacy. Those are just for a beginning. Please note that these actions were applied the first hundred years or so in America.

“... they can make divorce more difficult.”

As long as government is involved in the marriage business, I would argue that getting married should be made more difficult and getting divorced made easier.
