Is Netherlands no longer able to start war without permission from Germany?

Question

I stumbled upon this article, dated April 14 2016, titled "Germany Is Taking Over the Dutch Army".

The article says that

Huge portions of the Dutch military are being merged with the German Army, a process that many want to see rolled out across the whole Continent. Two of the Netherland’s three combat brigades have officially begun the process of joining the Bundeswehr.

...

This is a revolutionary change, not just for the Netherlands, but for Europe and, in time, the world. It is paving the way for a newly capable German-led military force.

The two nations are also extending this partnership to the sea. Germany and the Netherlands will share the Dutch Navy’s largest and most expensive ship, the Karel Doorman.

The same site has other articles about this same subject.

For example this article titled "Germany Is Building a European Army Before Your Eyes" (dated August 11th, 2014) says that

The Dutch Army is made up of three brigades, plus support staff and Special Forces. On June 12, one of those brigades, the 11th Airmobile, officially joined the German Army.

This was the first time ever that European country has handed part of its army over to another country. “Never before has a state renounced this elementary and integral part of its sovereignty,” wrote Die Welt’s political editor, Thorsten Jungholt.

Now, Germany is making it clear that this was not an isolated event. Instead, it is a pattern Germany intends to follow as it absorbs more units from foreign militaries. “Germany is driving the European Army Project” was the title of Jungholt’s Die Welt article.

And this article (undated), titled "Under Construction" says (emphasis added):

And beginning in 2014, the Dutch military’s advance guard will be commanded by Germans. The Dutch will no longer begin a war without German permission.

From this last article I noticed however that this is some kind of a religious publication, as the article says things like

The prophecies of the book of Revelation are being fulfilled before our eyes. Or, to put it another way, history is repeating itself. Germany is returning to its role as the premier military power in Europe.

Considering that these articles are now some years old but there has not been much news about Germany "building a European Army", I am thinking that this is either fake news or that the subject matter is being exaggerated.

Questions:

1. Have large portions of the Dutch armed forces been placed under German control?
2. If yes, is it correct that "The Dutch will no longer begin a war without German permission"?

Answer 1

The cited articles are quite a bit misleading in how they present and interpret the details, but it they are essentially true regarding the facts they are based on.

The German army has several joint ventures going.

With France the Franco-German Brigade was formed in 1987.

With mainly Poland and Denmark the Multinational Corps Northeast established in 1999.

With the Netherlands the I. German/Dutch Corps operational since 1995.

Answering subquestion 1:
The really new part, almost scandalised in the claim, is that indeed two whole brigades formally still part of the Army of the Netherlands are now placed under sole German control concerning organsiation and command structure. The 11th Airmobile Brigade (Netherlands) (own website) and the 43rd Mechanized Brigade (Netherlands) (own website, and German website) are organisationally part of the German Army since 2014 and 2016 respectively.

Whether this represents a large part as in the claim is answered by Wikipedia as follows:

2 of 3 Dutch Army Brigades are now under German Command. In 2014 the 11th Airmobile Brigade, was integrated into the Rapid Forces Division (Division Schnelle Kräfte), while the 43rd Mechanized Brigade began integration into the 1st Panzer Division (1. Panzerdivision) in 2016, with the intention that it is fully part of the German formation by the end of 2019. The Dutch-German military cooperation are seen as an example for setting up a European defense union.

Answering subquestion 2:
From the examples listed it should be clear that it is not really Germany alone that is building this European Army, although it may well be the biggest player in this game. The whole process of European integration was meant to prevent going to war with each other ever again. Since both countries are also members of NATO the concept of one member state unilaterally, that is without consulting or – better explicit approval – the others, beginning a war is frowned upon within this organisation anyway. Exceptions like the US, the UK and Turkey have to be noted though.
Given the current and developing army command structure it will be difficult for the Netherlands to join this list of exceptions.
Formally declaring any war is so twentieth century now. In recent years NATO or its members just invade territory or drop ordnance for security.
That the "Dutch will no longer begin a war without German permission" is also highly speculative to answer, as it concerns events in the future. But such behaviour would be against the signed treaties on and around this issue in any case. The stated goal of European military integration is that all EU members are on the same page regarding military issues, including "war":

Military of the European Union: The military of the European Union comprises the various cooperative structures that have been established between the armed forces of the member states, both intergovernmentally and within the institutional framework of the union; the Common Security and Defence Policy (CSDP) branch of the Common Foreign and Security Policy (CFSP).
Article 42 of the Treaty on European Union provides for substantial military integration within the institutional framework of the union:

Article 42.2 provides for complete integration, which would require unanimity in the European Council of heads of state or government and has as such been blocked by the United Kingdom, which is the main opponent of EU defence integration, in particular. (The United Kingdom is however scheduled to withdraw from the union in 2019.)
Article 42.6 enables the armed forces of a subset of member states to establish Permanent Structured Cooperation (PESCO) between themselves. In December 2017. 25 Member states of the European Union agreed to establish PESCO.

Whether this is or will be an army "led by Germany" seems to be a political judgement call left to reader.

Answer 2

The Wikipedia page on the German army structure says that two Dutch brigades are part of German divisions for training and instruction purposes. Nothing is said about who receives training and instruction.
