Here is a quote from Lenin on Imperialism that seems like it could be taken straight from the news. You are most probably already familiar with it, but perhaps others would like to read it too:
http://www.marxists.org/archive/lenin/works/1916/imp-hsc/ch06.htmThe principal feature of the latest stage of capitalism is the domination of monopolist associations of big employers. These monopolies are most firmly established when all the sources of raw materials are captured by one group, and we have seen with what zeal the international capitalist associations exert every effort to deprive their rivals of all opportunity of competing, to buy up, for example, ironfields, oilfields, etc. Colonial possession alone gives the monopolies complete guarantee against all contingencies in the struggle against competitors, including the case of the adversary wanting to be protected by a law establishing a state monopoly. The more capitalism is developed, the more strongly the shortage of raw materials is felt, the more intense the competition and the hunt for sources of raw materials throughout the whole world, the more desperate the struggle for the acquisition of colonies.

Finance capital is interested not only in the already discovered sources of raw materials but also in potential sources, because present-day technical development is extremely rapid, and land which is useless today may be improved tomorrow if new methods are devised (to this end a big bank can equip a special expedition of engineers, agricultural experts, etc.), and if large amounts of capital are invested. This also applies to prospecting for minerals, to new methods of processing up and utilising raw materials, etc., etc. Hence, the inevitable striving of finance capital to enlarge its spheres of influence and even its actual territory. In the same way that the trusts capitalise their property at two or three times its value, taking into account its “potential” (and not actual) profits and the further results of monopoly, so finance capital in general strives to seize the largest possible amount of land of all kinds in all places, and by every means, taking into account potential sources of raw materials and fearing to be left behind in the fierce struggle for the last remnants of independent territory, or for the repartition of those territories that have been already divided.
We've long since moved on from the crudities of outright colonialism, to the creation of weaker client states with malleable local governments.
