Although security and development complete each other, a region's security comes first in value before developing it, even when it's needed for a short residence/visit only. It's more challenging to live in an insecure place, than an undeveloped one. However, most development projects can be executed simultaneously alongside security ones, as "development is the best remedy for insecurity."
Only projects in areas with extreme/permanent risk should be postponed, until finding the best plan.
A region is insecure by different causes:
When managing a "politically insecure" region, by whatever external/internal threat, it may require more funding/privileges than other regions, which is worth it for the benefits it usually has (causing quarrelling "over").
For instance, developing remote border regions is important for many reasons:
A border region acting as a regional/international center can host people from many nationalities, for short or long terms, provided its identity and the sovereignty of the country it belongs to are protected first. Otherwise, uncontrolled social mobility can gradually cause political conflicts. Even other regions within a country can suffer similar conflicts, if population types are not distributed properly according to resources.
Remote regions deserve more development, by positive discrimination: receiving extra benefits until they are equal with others. They can be brought to the spotlight and have the priority of state's projects in many ways:
Gates, crossings and borders between provinces should be "secure yet flexible" for movement. There should be enough border control and checkpoints (permanent/changing), army barracks, ambushes, etc. Urbanization should be at least few kilometers from borders with other countries for safety, by keeping a buffer zone mostly left for the army. Even a smaller buffer zone between other regions within a country helps checking/controlling crimes, diseases, statistics, etc. Using technology for monitoring borders between regions is very useful, by satellite images, internet/radio communication, alongside air and land patrolling: helicopters, police vehicles, etc.
A mobile lifestyle best suits temporary residence in a new/unknown/insecure region, for exploratory or "cautionary" purposes, where escaping and moving options should be as much as those of settling. This requires more independence from traditional network and infrastructure.
When we give extra privileges to a region, its neighboring provinces are gradually privileged too:
In planning provinces, attention should be given most to the furthest point from the (usually congested) center, then to the point in mid-distance. Then the pattern goes the same with all the points in between: extreme, middle, extreme ... For examples, if A is the most privileged region, then on a line segment called ABCDEFG representing all regions en route to A, development should focus most on G, D, F, E, C, then B.
In a virtual circle-like country, whose capital lies at the center, the government should simultaneously develop the four furthest points from the center and from each other, which automatically creates main four radiuses (or two intersected diameters), and endless small axes connecting and urbanizing all points in the circle.
