If even one country legalizes gambling over the Internet, it is impossible to keep that service from any other person who has access to a computer and a modem. In light of the principles of national sovereignty, one country cannot tell another country not to offer Internet gambling. If one country prohibits Internet gambling, there will be a financial drain from that country into countries where such activity is legal. Thus, the current dynamics create pressure on nations to offer legalized gambling over the Internet.
Because international consensus on Internet gambling is unlikely, some governments will not be deterred from criminalizing the activity. This may be for several reasons. A government may believe for religious or social reasons that it cannot endorse or allow any form of lawful gambling. This position could prevail in countries that do not have secular governments. Likewise, a government may believe that while it cannot prohibit all Internet gambling, a prohibition would inhibit law-abiding citizens from participating and that law enforcement efforts may otherwise minimize its prevalence.
