No doubt we should have a plan to help sort out other countries and to be successful at it instead of half hearted about it. But who makes the plan? And the issue of stripping a country of power or honoring their sovernity in their land is an issue. I don't trust some of the ideals coming from the UN to enforce on other countries, and I doubt we will have a better view of how to help unless we're willing to go all in, and get really involved in that country. (Like how the US has done with Japan after they lost so much in WWII).
The thing is, they are already intervening in other countries. Its just that so much of the time the interventions do the opposite of what was intended. I'm wondering if they can't come up with a sensible plan that actually helps, perhaps they should just stay out of it (sanctions, jet sorties, drug wars). Maybe they should figure out how to fix the USA, then the skill to help others will be available. Things like prolonging the civil war in Syria have just led to millions of refugees invading Europe.
And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?
Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye?
Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye. Matthew 7:3-5 KJV
