Personally I think all of those dudes are making too big of a deal on the initial marriage finances.
It doesn't matter how much is spent on divorce costs or what prenuptial agreement says because the bulk of the value that these women will be taking is from child support.
Every single one of those dudes looks like the type to seed them up. So even if they get it in writing that the only thing their poor wives get after a divorce is a ham sandwich, they're still going to be taken to the cleaners with $3000/m child support .
None of those dudes look like they have substantial assets to protect. Otherwise they wouldn't be thugging it out with foreign women from cheap places. The only thing that can be protected is their income which will be forfeited by child support.
