The United Kingdom of Great Britain and Ireland
The London Protocol of 1852 has been violated with a most severely disrespectful degree of disregard by numerous parties to the agreement's signing. As is to be expected of when such agreements are abandoned, the result of this disrespect has been an outburst of war. The major powers of the German Confederation have attempted to exert their stature over the Kingdom of Denmark, in order to seize territories that they perceive as their own rightful possessions, on the basis of demographics. Denmark was not of the same mind with the Kingdoms of Prussia and Austria, nor was her dependable ally to the north.
The Kingdom of Denmark is not entirely innocent in relation to the violation of the London Protocol, both in letter and in spirit. In 1855, attempts were made by the Danish government to create a joint parliament ruling over the core of the Kingdom of Denmark alongside Schleswig-Holstein. This direction violation of the London Protocol is less grievous than the recent violation by the German Confederation; it is evident to all of the powers of Europe that the Kingdom of Prussia desires to annex all of Schleswig-Holstein into its expanse, German or no, seemingly contrary to the nationalistic character of the desired annexation. Being as it is that numerous parties on either side of this conflict are in the wrong in different respects, it is therefore most wise for all parties involved in the London Protocol of 1852 alongside all other relevant parties desiring peace in Europe to renegotiate terms and establish a definitive and long-standing border between the Kingdom of Denmark and the German Confederation, with no level of ambiguity regarding succession or suzerainty.
With this wisdom in mind, Her Majesty's Royal Navy has established itself a presence in the conflict area, and will engage in military force with the aggressing powers should they refuse to accept peace negotiations. A final solution to the question of Schleswig-Holstein must be reached, and it must be reached through dialogue, not through a military invasion and a unilateral annexation.
