Because the world in which I have lived for most of my life is in the world of infidels, I cannot openly acknowledge my sympathy for my Islamic Jihadist brothers. If fact, because of my position of power, I must conceal my sympathies. All I do to enable my brothers must be covert, known only to me and perhaps my wife and my closest confidant.
The first thing I would do is to never refer to the actions taken by the Islamic Jihadists as Islamic Jihadist terrorism, but always use the generic and non-identifying term of terrorist. I do not want to directly connect my brothers, for whom I have sympathy, as terrorists. These brothers are after all only doing the work as directed by the prophet so I cannot directly condemn them.
When I am given the opportunity, what I will do is justify the acts that are being done in the name of Allah by showing how the Christen world deserves what they are receiving because of the Crusades. An equivalency must be drawn because I believe it is just and proper. If I have the opportunity I will also have my underlings justify the actions of the Jihadists for attacking and killing those who defame the prophet by calling the actions of killing those who publicize the defaming material as rationale. In no way will I directly condemn anything done in the name of Allah but reinforce that the Muslim teachings of peace even though the prophet said all infidels must be killed.
I would also assist those who are carrying out the directives of eradicating all infidels. When given the opportunity I would give weapons to those I know would turn them over to the Jihadists because they would be unable to defend them. I would refuse to give weapons to those I know would use them effectively against my brothers. If I were forced into a position where I would have to attack the Jihadists, those for whom I have sympathy, and possibly harm them, I would agree to bomb the Jihadists, but be very selective in what could be bombed and tell the world it is so there is no collateral damage. I would also insist the Jihadists were warned in plenty of time of an attack so they would not get hurt and could minimize any damage. My bombing war would intentionally be very ineffective.
The Jihadists, and we who sympathize with them, understand much of the success of fulfilling the prophets commands is the effective use of terror tactics in the world of the infidel. I would assist these tactics by demanding when an act of terror using guns has been committed against the infidels, that the guns were the reason for the actions and therefore guns should be eliminated from a civilized society. This action makes the actions of the Jihadists brothers much safer for the brothers and would bring about even more carnage and mayhem when the infidel is unable to protect himself.
The more of these acts that can be committed against the infidel the better it is for the Jihadists work of carrying out the commands of the prophet. Therefore I would find ways to move committed followers of Allah into positions to perform the necessary work. One way to move these committed Jihadists into positions to perform these acts, would be to be sure they could move across borders easily. Border security must be negated. I would also use opportunities that presented themselves. For instance, if I could implement a refugee program claiming it was for humanitarian reasons, but knowing many of those posing as refugees would be committed Jihadists, I would do it immediately. I would know that those who opposed such a program would be labeled as inhumane and some politically correct phobia.
Yes, if I was a Jihadist sympathizer, and I wanted to fundamentally transform a free and independent infidel nation, these are the actions I would take.
